Market Insights

Dear Shareholder,

This semiannual report covers the six-month reporting period ended June 30, 2023 (the “reporting period”). On the subsequent pages, you will find details regarding investment results and a discussion of certain factors that affected performance during the reporting period.

Amid elevated inflation in many countries during the reporting period, the global economy faced challenges from higher interest rates, tighter credit conditions stemming from the turmoil in the banking sector (especially in the United States (“U.S.”)), and geopolitical concerns. While the U.S. economy showed signs of resilience, some European economies experienced slower growth over the reporting period.

Continued central bank efforts to combat inflation

While inflation remained elevated over the reporting period, many central banks raised interest rates to rein in rising prices. The U.S. Federal Reserve (the “Fed”) raised the federal funds rate at 10 consecutive meetings, beginning in March 2022 through May 2023. In June 2023, the Fed then paused from raising rates in order to “assess additional information and its implications for monetary policy.” Meanwhile, the Bank of England and European Central Bank raised interest rates for the 13^th and eighth consecutive time, respectively, as of June 2023. In contrast, the Bank of Japan maintained its accommodative monetary policy stance.

Mixed financial market returns

The yield on the benchmark 10-year U.S. Treasury declined over the reporting period, while 10-year bond yields in most other developed market countries increased. The overall global credit bond market delivered positive total returns. Higher-rated global bonds underperformed lower-rated bonds. Global equities rallied, while commodity prices were volatile and produced mixed returns. The U.S. dollar weakened against the euro and the British pound, but appreciated against the Japanese yen.

Amid evolving conditions, we will continue to work diligently to navigate global markets and manage the assets that you have entrusted with us. We encourage you to speak with your financial advisor about your goals, and visit global.pimco.com for our latest insights.

Sincerely,

Deborah A. DeCotis	Eric D. Johnson
Chair of the Board of Trustees	President

Total Returns of Certain Asset Classes for the Period Ended June 30, 2023

Past performance is no guarantee of future results. Unless otherwise noted, index returns reflect the reinvestment of income distributions and capital gains, if any, but do not reflect fees, brokerage commissions or other expenses of investing. It is not possible to invest directly in an unmanaged index.

Statements concerning financial market trends are based on current market conditions, which will fluctuate. There is no guarantee that these investment strategies will work under all market conditions or are appropriate for all investors and each investor should evaluate their ability to invest for the long-term, especially during periods of downturn in the market. Outlook and strategies are subject to change without notice.

Important Information About the Portfolios

We believe that bond funds have an important role to play in a well-diversified investment portfolio. It is important to note, however, that in an environment where interest rates may trend upward, rising rates would negatively impact the performance of most bond funds, and fixed income securities and other instruments held by a Portfolio are likely to decrease in value. A wide variety of factors can cause interest rates or yields of U.S. Treasury securities (or yields of other types of bonds) to rise (e.g., central bank monetary policies, inflation rates, general economic conditions, etc.). In addition, changes in interest rates can be sudden and unpredictable, and there is no guarantee that Portfolio management will anticipate such movement accurately. A Portfolio may lose money as a result of movements in interest rates.

As of the date of this report, interest rates in the United States and many parts of the world, including certain European countries, continue to increase. In efforts to combat inflation, the U.S. Federal Reserve raised interest rates multiple times in 2022 and 2023. Thus, the Portfolios currently face a heightened level of risk associated with rising interest rates and/or bond yields. This could be driven by a variety of factors, including but not limited to central bank monetary policies, changing inflation or real growth rates, general economic conditions, increasing bond issuances or reduced market demand for low yielding investments. Further, while bond markets have steadily grown over the past three decades, dealer inventories of corporate bonds are near historic lows in relation to market size. As a result, there has been a significant reduction in the ability of dealers to “make markets.”

Bond funds and individual bonds with a longer duration (a measure used to determine the sensitivity of a security’s price to changes in interest rates) tend to be more sensitive to changes in interest rates, usually making them more volatile than securities or funds with shorter durations. All of the factors mentioned above, individually or collectively, could lead to increased volatility and/or lower liquidity in the fixed income markets or negatively impact a Portfolio’s performance or cause a Portfolio to incur losses. As a result, a Portfolio may experience increased shareholder redemptions, which, among other things, could further reduce the net assets of the Portfolio.

Classifications of the Portfolios’ portfolio holdings in this report are made according to financial reporting standards. The classification of a particular portfolio holding as shown in the Allocation Breakdown and Schedule of Investments sections of this report may differ from the classification used for the Portfolios’ compliance calculations, including those used in the Portfolios’ prospectus, investment objectives, regulatory, and other investment limitations and policies, which may be based on different asset class, sector or geographical classifications. Each Portfolio is separately monitored for compliance with respect to prospectus and regulatory requirements.

The geographical classification of foreign (non-U.S.) securities in this report, if any, are classified by the country of incorporation of a holding. In certain instances, a security’s country of incorporation may be different from its country of economic exposure.

In February 2022, Russia launched an invasion of Ukraine. As a result, Russia and other countries, persons and entities that have provided material aid to Russia’s aggression against Ukraine, have been the subject of economic sanctions and import and export controls imposed by countries throughout the world, including the United States. Such measures have had and may continue to have an adverse effect on the Russian, Belarusian and other securities and economies, which may, in turn, negatively impact a Portfolio. The extent, duration and impact of Russia’s military action in Ukraine, related sanctions and retaliatory actions are difficult to ascertain, but could be significant and have severe adverse effects on the region, including significant adverse effects on the regional,

SEMIANNUAL REPORT JUNE 30, 2023 3

Important Information About the Portfolios (Cont.)

European, and global economies and the markets for certain securities and commodities, such as oil and natural gas, as well as other sectors. Further, a Portfolio may have investments in securities and instruments that are economically tied to the region and may have been negatively impacted by the sanctions and counter-sanctions by Russia, including declines in value and reductions in liquidity. The sanctions may cause a Portfolio to sell portfolio holdings at a disadvantageous time or price or to continue to hold investments that a Portfolio may no longer seek to hold. PIMCO will continue to actively manage these positions in the best interests of a Portfolio and its shareholders.

The Portfolios may invest in certain instruments that rely in some fashion upon the London Interbank Offered Rate (“LIBOR”). LIBOR was traditionally an average interest rate, determined by the ICE Benchmark Administration, that banks charge one another for the use of short-term money. In March 2021, the United Kingdom’s Financial Conduct Authority, which regulates LIBOR, announced plans to ultimately phase out the use of LIBOR. Although the transition process away from LIBOR for many instruments has been completed, some LIBOR use is continuing and there are potential effects related to the transition away from LIBOR or continued use of LIBOR on the Portfolios, or on certain instruments in which the Portfolios invest, which can be difficult to ascertain, and may vary depending on factors that include, but are not limited to: (i) existing fallback or termination provisions in individual contracts and (ii) whether, how, and when industry participants adopt new reference rates for affected instruments. The transition of investments from LIBOR to a replacement rate as a result of amendment, application of existing fallbacks, statutory requirements or otherwise may also result in a reduction in the value of certain instruments held by the Portfolios or a reduction in the effectiveness of related Portfolio transactions such as hedges. In addition, an instrument’s transition to a replacement rate could result in variations in the reported yields of the Portfolio that holds such instrument. Any such effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to the Portfolios.

U.S. and global markets recently have experienced increased volatility, including as a result of the recent failures of certain U.S. and non-U.S. banks, which could be harmful to a Portfolio and issuers in which it invests. For example, if a bank at which the Portfolio or issuer has an account fails, any cash or other assets in bank or custody accounts, which may be substantial in size, could be temporarily inaccessible or permanently lost by the Portfolio or issuer. If a bank that provides a subscription line credit facility, asset-based facility, other credit facility and/or other services to an issuer or to a fund fails, the issuer or fund could be unable to draw funds under its credit facilities or obtain replacement credit facilities or other services from other lending institutions with similar terms.

Issuers in which a Portfolio may invest can be affected by volatility in the banking sector. Even if banks used by issuers in which a Portfolio invests remain solvent, continued volatility in the banking sector could contribute to, cause or intensify an economic recession, increase the costs of capital and banking services or result in the issuers being unable to obtain or refinance indebtedness at all or on as favorable terms as could otherwise have been obtained. Conditions in the banking sector are evolving, and the scope of any potential impacts to a Portfolio and issuers, both from market conditions and also potential legislative or regulatory responses, are uncertain. Such conditions and responses, as well as a changing interest rate environment, can contribute to decreased market liquidity and erode the value of certain holdings, including those of U.S. and non-U.S. banks. Continued market volatility and uncertainty and/or a downturn in market and economic and financial conditions, as a result of developments in the banking sector or otherwise (including as a result of delayed access to cash or credit facilities), could have an adverse impact on a Portfolio and issuers in which it invests.

On each Portfolio Summary page in this Shareholder Report, the Average Annual Total Return table and Cumulative Returns chart measure performance assuming that all dividend and capital gain distributions were reinvested. Returns do not reflect the deduction of taxes that a shareholder would pay on (i) Portfolio distributions or (ii) the redemption of Portfolio shares. Total return for a period of more than one year represents the average annual total return. Performance shown is net of fees and expenses. The figures in the line graph are calculated at net asset value and assume the investment of $10,000 at the end of the month that a Portfolio commenced operations. Each Portfolio measures its performance against a broad-based securities market index (“benchmark index”). Each benchmark index does not take into account fees, expenses or taxes. Historical performance for a Portfolio may have been positively impacted by fee waivers or expense limitations in place during some or all of the periods shown, if applicable. Future performance (including total return or yield) and distributions may be negatively impacted by the termination or reduction of any such fee waivers or expense limitations.

The dividend rate that a Portfolio pays on its common shares may vary as portfolio and market conditions change, and will depend on a number of factors, including without limit the amount of a Portfolio’s undistributed net investment income and net short- and long-term capital gains, as well as the costs of any leverage obtained by a Portfolio. As portfolio and market conditions change, the rate of distributions on the common shares and a Portfolio’s dividend policy could change. There can be no assurance that a change in market conditions or other factors will not result in a change in a Portfolio’s distribution rate or that the rate will be sustainable in the future.

The following table discloses the commencement of operations and diversification status of each Portfolio:

The Trustees are responsible generally for overseeing the management of the Trust. The Trustees authorize the Trust to enter into service agreements with PIMCO as the Investment Adviser and Administrator, PIMCO Investments LLC and other service providers in order to provide, and in some cases authorize service providers to procure through other parties, necessary or desirable services on behalf of the Trust and the Portfolios. Shareholders are not parties to or third-party beneficiaries of such service agreements. Neither a Portfolio’s prospectus, summary prospectus, the Trust’s Statement of Additional Information (“SAI”), any contracts filed as exhibits to the Trust’s registration statement, nor any other communications, disclosure documents or regulatory filings (including this report) from or on behalf of the Trust or a Portfolio creates a contract between or among any shareholders of a Portfolio, on the one hand, and the Trust, a Portfolio, a service provider to the Trust or a Portfolio, and/or the Trustees or officers of the Trust, on the other hand.

The Trustees (or the Trust and its officers, service providers or other delegates acting under authority of the Trustees) may amend its most recent or use a new prospectus, summary prospectus or SAI with respect to a Portfolio or the Trust, and/or amend, file and/or issue any other communications,

disclosure documents or regulatory filings, and may amend or enter into any contracts to which the Trust or a Portfolio is a party, and interpret the investment objective(s), policies, restrictions and contractual provisions applicable to any Portfolio, without shareholder input or approval, except in circumstances in which shareholder approval is specifically required by law (such as changes to fundamental investment policies) or where a shareholder approval requirement is specifically disclosed in the Trust’s then-current prospectus or SAI.

An investment in a Portfolio is not a deposit of a bank and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. It is possible to lose money on investments in a Portfolio.

PIMCO has adopted written proxy voting policies and procedures (“Proxy Policy”) as required by Rule 206(4)-6 under the Investment Advisers Act of 1940. The Proxy Policy has been adopted by the Portfolios as the policies and procedures that PIMCO will use when voting proxies on behalf of the Portfolios. A description of the policies and procedures that PIMCO uses to vote proxies relating to portfolio securities of each Portfolio, and information about how each Portfolio voted proxies relating to portfolio securities held during the most recent twelve-month period ended June 30, are available without charge, upon request, by calling the Portfolios at (888) 87-PIMCO, on the Portfolios’ website at www.pimco.com/FISH, and on the Securities and Exchange Commission’s (“SEC”) website at www.sec.gov.

The Portfolios file portfolio holdings information with the SEC on Form N-PORT within 60 days of the end of each fiscal quarter. The Portfolios’ complete schedule of securities holdings as of the end of each fiscal quarter will be made available to the public on the SEC’s website at www.sec.gov and on PIMCO’s website at www.pimco.com/FISH, and will be made available, upon request, by calling PIMCO at (888) 87-PIMCO.

SEC rules allow shareholder reports to be delivered to investors by providing access to such reports online free of charge and by mailing a notice that the report is electronically available. Investors may elect to receive all future reports in paper free of charge by contacting their financial intermediary. Any election to receive reports in paper will apply to all portfolios held in the investor’s account at the financial intermediary.

In May 2022, the SEC proposed amendments to a current rule governing portfolio naming conventions. In general, the current rule requires portfolios with certain types of names to adopt a policy to invest at least 80% of their assets in the type of investment suggested by the name. The proposed amendments would expand the scope of the current rule in a number of ways that would result in an expansion of the types of portfolio names that would require the portfolio to adopt an 80% investment policy under the rule. Additionally, the proposed amendments would modify the circumstances under which a portfolio may deviate from its 80% investment policy and address the use and valuation of derivatives instruments for purposes of the rule. The proposal’s impact on the Portfolios will not be known unless and until any final rulemaking is adopted.

In May 2022, the SEC proposed a framework that would require certain registered portfolios (such as the Portfolios) to disclose their environmental, social, and governance (“ESG”) investing practices. Among other things, the proposed requirements would mandate that portfolios meeting three pre-defined classifications (i.e., integrated, ESG focused and/or impact funds) provide prospectus and

6 PIMCO MANAGED ACCOUNTS TRUST

shareholder report disclosure related to the ESG factors, criteria and processes used in managing the portfolio. The proposal’s impact on the Portfolios will not be known unless and until any final rulemaking is adopted.

In October 2022, the SEC adopted changes to the mutual fund and exchange-traded fund (“ETF”) shareholder report and registration statement disclosure requirements and the registered fund advertising rules, which will impact the disclosures provided to shareholders. The rule amendments are effective as of January 24, 2023, but the SEC is providing an 18-month compliance period following the effective date for such amendments other than those addressing fee and expense information in advertisements that might be materially misleading.

In November 2022, the SEC proposed rule amendments which, among other things, would require funds to adopt swing pricing in order to mitigate dilution of shareholders’ interests in a fund by requiring the adjustment of fund net asset value per share to pass on costs stemming from shareholder purchase or redemption activity. In addition the proposed rule would amend the liquidity rule framework. The proposal’s impact on the Portfolios will not be known unless and until any final rulemaking is adopted.

In November 2022, the SEC adopted amendments to Form N-PX under the Act to improve the utility to investors of proxy voting information reported by mutual funds, ETFs and certain other funds. The rule amendments will expand the scope of funds’ Form N-PX reporting obligations, subject managers to Form N-PX reporting obligations for “Say on Pay” votes, enhance Form N-PX disclosures, permit joint reporting by funds, managers and affiliated managers on Form N-PX; and require website availability of fund proxy voting records. The amendments will become effective on July 1, 2024. Funds and managers will be required to file their first reports covering the period from July 1, 2023 to June 30, 2024 on amended Form N-PX by August 31, 2024.

Investment Objective

The Portfolio seeks maximum real return, consistent with preservation of real capital and prudent investment management.

Portfolio Insights

The following affected performance (on a gross basis) during the reporting period:

» Exposure to U.S. Treasury Inflation-Protected Securities (“TIPS”) contributed to absolute returns, as TIPS posted positive returns.

» Overweight exposure to U.S. breakeven inflation (“BEI”), the yield differential between nominal government bonds and like-maturity inflation-linked bonds, most notably early in the period, contributed to relative performance, as U.S. BEI moved higher.

» Overweight exposure to Japanese BEI, contributed to relative performance, as U.S. BEI moved higher.

» Exposure to non-agency residential mortgage-backed securities contributed to relative performance, as spreads narrowed.

» Underweight exposure to Japanese interest rates, specifically larger underweight exposure to intermediate maturities in March 2023 relative to smaller underweight exposure earlier and later in the period, detracted from relative performance, as Japanese interest rates declined in March 2023.

» Exposure to Danish covered bonds detracted from relative performance, as spreads widened.

» Overweight exposure to the Japanese yen relative to the U.S. dollar detracted from relative performance, as the Japanese yen depreciated relative to the U.S. dollar.

Investment Objective

The Portfolio seeks high current income exempt from U.S. federal income tax consistent with prudent investment management. Total return/capital appreciation is a secondary objective.

Portfolio Insights

The following affected performance (on a gross basis) during the reporting period:

» Yield curve strategies contributed to performance, as interest rates broadly rose.

» Overweight exposure to the industrial revenue sector contributed to performance, as the sector outperformed the broader municipal market.

» Overweight exposure to the special tax sector contributed to performance, as the sector outperformed the broader municipal market.

» Underweight exposure to the lease-backed sector detracted from performance, as the sector outperformed the broader municipal market.

» Underweight exposure to the transportation sector detracted from performance, as the sector outperformed the broader municipal market.

» Security selection within the education sector detracted from performance, as the sector underperformed the broader municipal market.

Expense Examples

Example

As a shareholder of a Portfolio, you incur two types of costs: (1) transaction costs and (2) ongoing costs, including investment advisory fees, supervisory and administrative fees, distribution and/or service (12b-1) fees (if applicable), and other Portfolio expenses. The Example is intended to help you understand your ongoing costs (in dollars) of investing in the Portfolio and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period indicated, which for all Portfolios is from January 1, 2023 to June 30, 2023, unless noted otherwise in the table and footnotes below.

Actual Expenses

The information in the table under the heading “Actual” provides information about actual account values and actual expenses. You may use the information in these rows, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.60), then multiply the result by the number in the appropriate row for your Portfolio in the column titled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The information in the table under the heading “Hypothetical (5% return before expenses)” provides information about hypothetical account values and hypothetical expenses based on a Portfolio’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Portfolio’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in a Portfolio and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs. Therefore, the information under the heading “Hypothetical (5% return before expenses)” is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Expense ratios may vary period to period because of various factors, such as an increase in expenses that are not covered by the investment advisory fees and supervisory and administrative fees, such as fees and expenses of the independent trustees and their counsel, extraordinary expenses and interest expense.

* Expenses Paid During Period are equal to the net annualized expense ratio for the Portfolio, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

** Net Annualized Expense Ratio is reflective of any applicable contractual fee waivers and/or expense reimbursements or voluntary fee waivers. Details regarding fee waivers, if any, can be found in Note 9, Fees and Expenses, in the Notes to Financial Statements.

^(a) The Net Annualized Expense Ratio reflected in the expense example above includes 0.11% of non-cash interest expense as shown in the Financial Statements. If the example excluded non-cash interest expense, Expenses Paid During Period would have been $0.00 for Actual Performance and $0.00 for Hypothetical Performance. The additional non-cash interest expense does not reflect actual expenses paid by the Portfolio, but instead is offset by additional interest income recorded by the Portfolio in Tender Option Bonds (“TOBs”) transactions accounted for as secured borrowings. Refer to Note 5, Borrowings and Other Financing Transactions, in the Notes to Financial Statements for additional information regarding TOBs.

The actual tax characterization of distributions paid is determined at the end of the fiscal year. See Note 2, Distributions to Shareholders, in the Notes to Financial Statements for more information.

^(d)  Includes adjustments required by U.S. GAAP and may differ from net asset values and performance reported elsewhere by the Portfolios. Additionally, excludes initial sales charges and contingent deferred sales charges.

^(e)  The calculation assumes that all income dividends and capital gain distributions, if any, have been reinvested. Total return does not reflect broker commissions or “wrap fee” charges. Total investment return for a period of less than one year is not annualized.

^(f)  The financial statements reflect the fact that no investment management fees or expenses are incurred by the Portfolios. The Portfolios are an integral part of “wrap-fee” programs sponsored by investment advisers and/or broker-dealers unaffiliated with the Portfolios and PIMCO. Participants in these programs pay a “wrap” fee to the sponsor of the program.

(i) Securities with an aggregate market value of $11,737 and cash of $9,003 have been pledged as collateral for exchange-traded and centrally cleared financial derivative instruments as of June 30, 2023. See Note 8, Master Netting Arrangements, in the Notes to Financial Statements for more information.

⁽¹⁾ If the Portfolio is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Portfolio will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

⁽²⁾  Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on sovereign issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

⁽³⁾  The maximum potential amount the Portfolio could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

⁽⁴⁾  The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(k) Securities with an aggregate market value of $1,986 have been pledged as collateral for financial derivative instruments as governed by International Swaps and Derivatives Association, Inc. master agreements as of June 30, 2023.

⁽¹⁾ If the Portfolio is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Portfolio will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

⁽²⁾ Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on sovereign issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

⁽³⁾ The maximum potential amount the Portfolio could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

⁽⁴⁾ The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

⁽⁵⁾ Net Exposure represents the net receivable/(payable) that would be due from/to the counterparty in the event of default. Exposure from OTC financial derivative instruments can only be netted across transactions governed under the same master agreement with the same legal entity. See Note 8, Master Netting Arrangements, in the Notes to Financial Statements for more information.

Cash of $956 has been pledged as collateral for exchange-traded and centrally cleared financial derivative instruments as of June 30, 2023. See Note 8, Master Netting Arrangements, in the Notes to Financial Statements for more information.

⁽¹⁾ If the Portfolio is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Portfolio will either (i) receive from the seller of protection an amount equal to the notional amount of the swap and deliver the referenced obligation or underlying securities comprising the referenced index or (ii) receive a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

⁽²⁾ The maximum potential amount the Portfolio could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

⁽³⁾ The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

⁽¹⁾ If the Portfolio is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Portfolio will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

⁽²⁾  Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on sovereign issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

⁽³⁾  The maximum potential amount the Portfolio could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

⁽⁴⁾  The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

⁽¹⁾ If the Portfolio is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Portfolio will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay

a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

⁽²⁾ Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

⁽³⁾ The maximum potential amount the Portfolio could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

⁽⁴⁾ The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

⁽⁵⁾ This instrument has a forward starting effective date. See Note 2, Securities Transactions and Investment Income, in the Notes to Financial Statements for further information.

Notes to Financial Statements

1. ORGANIZATION

PIMCO Managed Accounts Trust (the “Trust”), was organized as a Massachusetts business trust on November 3, 1999. The Trust is comprised of Fixed Income SHares (“FISH”): Series C, Series LD, Series M, Series R and Series TE (each a “Portfolio” or “Series” and collectively the “Portfolios” or “Series”). Each Portfolio has authorized an unlimited number of shares of beneficial interest with $0.001 par value. Pacific Investment Management Company LLC (“PIMCO” or the “Adviser”) serves as the Portfolios’ investment adviser and administrator.

Hereinafter, the Board of Trustees of the Portfolios shall be collectively referred to as the “Board.”

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently followed by each Portfolio in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Each Portfolio is treated as an investment company under the reporting requirements of U.S. GAAP. The functional and reporting currency for the Portfolios is the U.S. dollar. The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

(a) Securities Transactions and Investment Income  Securities transactions are recorded as of the trade date for financial reporting purposes. Securities purchased or sold on a when-issued or delayed-delivery basis may be settled beyond a standard settlement period for the security after the trade date. Realized gains (losses) from securities sold are recorded on the identified cost basis. Dividend income is recorded on the ex-dividend date, except certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as a Portfolio is informed of the ex-dividend date. Interest income, adjusted for the accretion of discounts and amortization of premiums, is recorded on the accrual basis from settlement date, with the exception of securities with a forward starting effective date, where interest income is recorded on the accrual basis from effective date. For convertible securities, premiums attributable to the conversion feature are not amortized. Estimated tax liabilities on certain foreign securities are recorded on an accrual basis and are reflected as components of interest income or net change in unrealized appreciation (depreciation) on investments on the Statements of Operations, as appropriate. Tax liabilities realized as a result of such security sales are reflected as a component of net realized gain (loss) on investments on the Statements of Operations. Paydown gains (losses) on mortgage-related and other asset-backed securities, if any, are recorded as components of interest income on the Statements of Operations. Income or short-term capital gain distributions received from registered investment companies, if any, are recorded as dividend income. Long-term capital gain distributions received from registered investment companies, if any, are recorded as realized gains.

Debt obligations may be placed on non-accrual status and related interest income may be reduced by ceasing current accruals and writing off interest receivable when the collection of all or a portion of interest has become doubtful based on consistently applied procedures. A debt obligation is removed from non-accrual status when the issuer resumes interest payments or when collectability of interest is probable.

June 30, 2023

(b) Foreign Currency Translation  The market values of foreign securities, currency holdings and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars based on the current exchange rates each business day. Purchases and sales of securities and income and expense items denominated in foreign currencies, if any, are translated into U.S. dollars at the exchange rate in effect on the transaction date. The Portfolios do not separately report the effects of changes in foreign exchange rates from changes in market prices on securities held. Such changes are included in net realized gain (loss) and net change in unrealized appreciation (depreciation) from investments on the Statements of Operations. The Portfolios may invest in foreign currency-denominated securities and may engage in foreign currency transactions either on a spot (cash) basis at the rate prevailing in the currency exchange market at the time or through a forward foreign currency contract. Realized foreign exchange gains (losses) arising from sales of spot foreign currencies, currency gains (losses) realized between the trade and settlement dates on securities transactions and the difference between the recorded amounts of dividends, interest, and foreign withholding taxes and the U.S. dollar equivalent of the amounts actually received or paid are included in net realized gain (loss) on foreign currency transactions on the Statements of Operations. Net unrealized foreign exchange gains (losses) arising from changes in foreign exchange rates on foreign denominated assets and liabilities other than investments in securities held at the end of the reporting period are included in net change in unrealized appreciation (depreciation) on foreign currency assets and liabilities on the Statements of Operations.

(c) Distributions to Shareholders  Each Portfolio distributes substantially all of its net investment income to shareholders in the form of dividends. Dividends are declared daily and distributed monthly, generally on the last business day of the month. In addition, each Portfolio distributes any net capital gains it earns from the sale of portfolio securities to shareholders no less frequently than annually. Net short-term capital gains may be paid more frequently. A Portfolio may revise its distribution policy or postpone the payment of distributions at any time.

Income distributions and capital gain distributions are determined in accordance with income tax regulations which may differ from U.S. GAAP. Differences between tax regulations and U.S. GAAP may cause timing differences between income and capital gain recognition. Further, the character of investment income and capital gains may be different for certain transactions under the two methods of accounting. As a result, income distributions and capital gain distributions declared during a fiscal period may differ significantly from the net investment income (loss) and realized gains (losses) reported on each Portfolio’s annual financial statements presented under U.S. GAAP.

Separately, if a Portfolio determines or estimates, as applicable, that a portion of a distribution may be comprised of amounts from sources other than net investment income in accordance with its policies, accounting records (if applicable), and accounting practices, the Portfolio will notify shareholders of the estimated composition of such distribution through a Section 19 Notice. For these purposes, a Portfolio determines or estimates, as applicable, the source or sources from which a distribution is paid, to the close of the period as of which it is paid, in reference to its internal accounting records and related accounting practices. If, based on such accounting records and practices, it is determined or estimated, as applicable, that a particular distribution does not include capital gains or paid-in surplus or other capital sources, a Section 19 Notice generally would not be issued. It is important to note that differences exist between a Portfolio’s daily internal accounting records and practices, a Portfolio’s financial statements presented in accordance with U.S. GAAP,

SEMIANNUAL REPORT JUNE 30, 2023 97

Notes to Financial Statements (Cont.)

and recordkeeping practices under income tax regulations. For instance, a Portfolio’s internal accounting records and practices may take into account, among other factors, tax-related characteristics of certain sources of distributions that differ from treatment under U.S. GAAP. Examples of such differences may include but are not limited to, for certain Portfolios, the treatment of periodic payments under interest rate swap contracts. Accordingly, among other consequences, it is possible that a Portfolio may not issue a Section 19 Notice in situations where the Portfolio’s financial statements prepared later and in accordance with U.S. GAAP and/or the final tax character of those distributions might later report that the sources of those distributions included capital gains and/or a return of capital. Please visit www.pimco.com for the most recent Section 19 Notice, if applicable, for additional information regarding the estimated composition of distributions. Final determination of a distribution’s tax character will be provided to shareholders when such information is available.

Distributions classified as a tax basis return of capital at a Portfolio’s fiscal year end, if any, are reflected on the Statements of Changes in Net Assets and have been recorded to paid in capital on the Statements of Assets and Liabilities. In addition, other amounts have been reclassified between distributable earnings (accumulated loss) and paid in capital on the Statements of Assets and Liabilities to more appropriately conform U.S. GAAP to tax characterizations of distributions.

(d) New Accounting Pronouncements and Regulatory Updates  In March 2020, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”), ASU 2020-04, which provides optional guidance to ease the potential accounting burden associated with transitioning away from the London Interbank Offered Rate and other reference rates that are expected to be discontinued. ASU 2020-04 is effective for certain reference rate-related contract modifications that occurred during the period March 12, 2020 through December 31, 2022. In March 2021, the administrator for LIBOR announced the extension of the publication of a majority of the USD LIBOR settings to June 30, 2023. In December 2022, FASB issued ASU 2022-06, which includes amendments to extend the duration of the LIBOR transition relief to December 31, 2024, after which entities will no longer be permitted to apply the reference rate reform relief. Management is continuously evaluating the potential effect a discontinuation of LIBOR could have on the Portfolios’ investments and has determined that it is unlikely the ASU’s adoption will have a material impact on the Portfolios’ financial statements.

In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820), which affects all entities that have investments in equity securities measured at fair value that are subject to a contractual sale restriction. The amendments in ASU 2022-03 clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring the fair value. The amendments also require additional disclosures for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with Topic 820. The effective date for the amendments in ASU 2022-03 is for fiscal years beginning after December 15, 2023 and interim periods within those fiscal years. At this time, management is evaluating the implications of these changes on the financial statements.

In October 2022, the U.S. Securities and Exchange Commission (“SEC”) adopted changes to the mutual fund and ETF shareholder report and registration statement disclosure requirements and the registered fund advertising rules, which will change the disclosures provided to shareholders. The

(Unaudited)

June 30, 2023

rule is effective as of January 24, 2023, but the SEC is providing an 18-month compliance period after the effective date other than for rule amendments addressing fee and expense information in advertisements that might be materially misleading. At this time, management is evaluating the implications of these changes on the financial statements.

The SEC made a final ruling on February 15, 2023 to adopt proposed amendments to the Settlement Cycle Rule (Rule 15c6-1) and other related rules under the Securities Exchange Act of 1934, as amended, to shorten the standard settlement cycle for most broker-dealer transactions from two business days after the trade date (T+2) to one business days after the trade date (T+1). The effective date was May 5, 2023, and the compliance date for the amendments is May 28, 2024. At this time, management is evaluating the implications of these changes on the financial statements.

3. INVESTMENT VALUATION AND FAIR VALUE MEASUREMENTS

(a) Investment Valuation Policies The NAV of a Portfolio’s shares, or each of their respective share classes as applicable, is determined by dividing the total value of portfolio investments and other assets attributable to the Portfolio or class, less any liabilities, as applicable, by the total number of shares outstanding.

On each day that the New York Stock Exchange (“NYSE”) is open, a Portfolio’s shares are ordinarily valued as of the close of regular trading (normally 4:00 p.m., Eastern time) (“NYSE Close”). Information that becomes known to the Portfolios or their agents after the time as of which NAV has been calculated on a particular day will not generally be used to retroactively adjust the price of a security or the NAV determined earlier that day. If regular trading on the NYSE closes earlier than scheduled, each Portfolio may calculate its NAV as of the earlier closing time or calculate its NAV as of the NYSE Close for that day. Each Portfolio generally does not calculate its NAV on days on which the NYSE is not open for business. If the NYSE is closed on a day it would normally be open for business, each Portfolio may calculate its NAV as of the NYSE Close for such day or such other time that the Portfolio may determine.

For purposes of calculating NAV, portfolio securities and other assets for which market quotations are readily available are valued at market value. A market quotation is readily available only when that quotation is a quoted price (unadjusted) in active markets for identical investments that the Portfolios can access at the measurement date, provided that a quotation will not be readily available if it is not reliable. Market value is generally determined on the basis of official closing prices or the last reported sales prices. The Portfolios will normally use pricing data for domestic equity securities received shortly after the NYSE Close and do not normally take into account trading, clearances or settlements that take place after the NYSE Close. A foreign (non-U.S.) equity security traded on a foreign exchange or on more than one exchange is typically valued using pricing information from the exchange considered by PIMCO to be the primary exchange. If market value pricing is used, a foreign (non-U.S.) equity security will be valued as of the close of trading on the foreign exchange, or the NYSE Close, if the NYSE Close occurs before the end of trading on the foreign exchange.

Investments for which market quotations are not readily available are valued at fair value as determined in good faith pursuant to Rule 2a-5 under the Act. As a general principle, the fair value

SEMIANNUAL REPORT JUNE 30, 2023 99

Notes to Financial Statements (Cont.)

of a security or other asset is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Pursuant to Rule 2a-5, the Board has designated PIMCO as the valuation designee (“Valuation Designee”) for each Portfolio to perform the fair value determination relating to all Portfolio investments. PIMCO may carry out its designated responsibilities as Valuation Designee through various teams and committees. The Valuation Designee’s policies and procedures govern the Valuation Designee’s selection and application of methodologies for determining and calculating the fair value of Portfolio investments. The Valuation Designee may value portfolio securities for which market quotations are not readily available and other portfolio assets utilizing inputs from pricing services, quotation reporting systems, valuation agents and other third-party sources (together, “Pricing Sources”).

Domestic and foreign (non-U.S.) fixed income securities, non-exchange traded derivatives, and equity options are normally valued on the basis of quotes obtained from brokers and dealers or Pricing Sources using data reflecting the earlier closing of the principal markets for those securities. Prices obtained from Pricing Sources may be based on, among other things, information provided by market makers or estimates of market values obtained from yield data relating to investments or securities with similar characteristics. Certain fixed income securities purchased on a delayed-delivery basis are marked to market daily until settlement at the forward settlement date. Exchange-traded options, except equity options, futures and options on futures are valued at the settlement price determined by the relevant exchange. Swap agreements are valued on the basis of bid quotes obtained from brokers and dealers or market-based prices supplied by Pricing Sources. With respect to any portion of a Portfolio’s assets that are invested in one or more open-end management investment companies (other than ETFs), the Portfolio’s NAV will be calculated based on the NAVs of such investments.

If a foreign (non-U.S.) equity security’s value has materially changed after the close of the security’s primary exchange or principal market but before the NYSE Close, the security may be valued at fair value. Foreign (non-U.S.) equity securities that do not trade when the NYSE is open are also valued at fair value. With respect to foreign (non-U.S.) equity securities, a Portfolio may determine the fair value of investments based on information provided by Pricing Sources, which may recommend fair value or adjustments with reference to other securities, indexes or assets. In considering whether fair valuation is required and in determining fair values, the Valuation Designee may, among other things, consider significant events (which may be considered to include changes in the value of U.S. securities or securities indexes) that occur after the close of the relevant market and before the NYSE Close. A Portfolio may utilize modeling tools provided by third-party vendors to determine fair values of foreign (non-U.S.) securities. For these purposes, unless otherwise determined by the Valuation Designee, any movement in the applicable reference index or instrument (“zero trigger”) between the earlier close of the applicable foreign market and the NYSE Close may be deemed to be a significant event, prompting the application of the pricing model (effectively resulting in daily fair valuations). Foreign exchanges may permit trading in foreign (non-U.S.) equity securities on days when a Portfolio is not open for business, which may result in a Portfolio’s portfolio investments being affected when shareholders are unable to buy or sell shares.

Whole loans may be fair valued using inputs that take into account borrower- or loan-level data (e.g., credit risk of the borrower) that is updated periodically throughout the life of each individual loan, any new borrower- or loan-level data received in written reports periodically by a Portfolio

100 PIMCO MANAGED ACCOUNTS TRUST

(Unaudited)

June 30, 2023

normally will be taken into account in calculating the NAV. A Portfolio’s whole loan investments, including those originated by a Portfolio, generally are fair valued in accordance with procedures approved by the Board.

Investments valued in currencies other than the U.S. dollar are converted to the U.S. dollar using exchange rates obtained from Pricing Sources. As a result, the value of such investments and, in turn, the NAV of a Portfolio’s shares may be affected by changes in the value of currencies in relation to the U.S. dollar. The value of investments traded in markets outside the United States or denominated in currencies other than the U.S. dollar may be affected significantly on a day that a Portfolio is not open for business. As a result, to the extent that a Portfolio holds foreign (non-U.S.) investments, the value of those investments may change at times when shareholders are unable to buy or sell shares and the value of such investments will be reflected in each Portfolio’s next calculated NAV.

Fair valuation may require subjective determinations about the value of a security. While the Trust’s and Valuation Designee’s policies and procedures are intended to result in a calculation of a Portfolio’s NAV that fairly reflects security values as of the time of pricing, the Trust cannot ensure that fair values accurately reflect the price that a Portfolio could obtain for a security if it were to dispose of that security as of the time of pricing (for instance, in a forced or distressed sale). The prices used by a Portfolio may differ from the value that would be realized if the securities were sold.

(b) Fair Value Hierarchy  U.S. GAAP describes fair value as the price that a Portfolio would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. It establishes a fair value hierarchy that prioritizes inputs to valuation methods and requires disclosure of the fair value hierarchy, separately for each major category of assets and liabilities, that segregates fair value measurements into levels (Level 1, 2 or 3). The inputs or methodology used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. Levels 1, 2 and 3 of the fair value hierarchy are defined as follows:

^∎  Level 1 — Quoted prices (unadjusted) in active markets or exchanges for identical assets and liabilities.

^∎  Level 2 — Significant other observable inputs, which may include, but are not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market corroborated inputs.

^∎  Level 3 — Significant unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available, which may include assumptions made by the Valuation Designee that are used in determining the fair value of investments.

In accordance with the requirements of U.S. GAAP, the amounts of transfers into and out of Level 3, if material, are disclosed in the Notes to Schedule of Investments for each respective Portfolio.

For fair valuations using significant unobservable inputs, U.S. GAAP requires a reconciliation of the beginning to ending balances for reported fair values that presents changes attributable to realized gain (loss), unrealized appreciation (depreciation), purchases and sales, accrued discounts (premiums), and transfers into and out of the Level 3 category during the period. The end of period

SEMIANNUAL REPORT JUNE 30, 2023 101

Notes to Financial Statements (Cont.)

value is used for the transfers between Levels of a Portfolio’s assets and liabilities. Additionally, U.S. GAAP requires quantitative information regarding the significant unobservable inputs used in the determination of fair value of assets or liabilities categorized as Level 3 in the fair value hierarchy. In accordance with the requirements of U.S. GAAP, a fair value hierarchy, and if material, a Level 3 reconciliation and details of significant unobservable inputs, have been included in the Notes to Schedule of Investments for each respective Portfolio.

(c) Valuation Techniques and the Fair Value Hierarchy

Level 1, Level 2 and Level 3 trading assets and trading liabilities, at fair value The valuation methods (or “techniques”) and significant inputs used in determining the fair values of portfolio securities or other assets and liabilities categorized as Level 1, Level 2 and Level 3 of the fair value hierarchy are as follows:

Common stocks, ETFs, exchange-traded notes and financial derivative instruments, such as futures contracts, rights and warrants, or options on futures that are traded on a national securities exchange, are stated at the last reported sale or settlement price on the day of valuation. To the extent these securities are actively traded and valuation adjustments are not applied, they are categorized as Level 1 of the fair value hierarchy. Investments valued (denominated) in currencies other than the U.S. dollar are converted to the U.S. dollar using exchange rates (currency spot and forward rates) obtained from Pricing Sources. As a result, the NAV of a Portfolio’s shares may be affected by changes in the value of currencies in relation to the U.S. dollar. The value of securities traded in markets outside the United States or denominated in currencies other than the U.S. dollar may be affected significantly on a day that the Trust is not open for business.

Investments in registered open-end investment companies (other than ETFs) will be valued based upon the NAVs of such investments and are categorized as Level 1 of the fair value hierarchy. Investments in unregistered open-end investment companies will be calculated based upon the NAVs of such investments and are considered Level 1 provided that the NAVs are observable, calculated daily and are the value at which both purchases and sales will be conducted.

Fixed income securities including corporate, convertible and municipal bonds and notes, U.S. government agencies, U.S. treasury obligations, sovereign issues, bank loans, convertible preferred securities and non-U.S. bonds are normally valued on the basis of quotes obtained from brokers and dealers or Pricing Sources that use broker-dealer quotations, reported trades or valuation estimates from their internal pricing models. The Pricing Sources’ internal models use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar assets. Securities that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Fixed income securities purchased on a delayed-delivery basis or as a repurchase commitment in a sale-buyback transaction are marked to market daily until settlement at the forward settlement date and are categorized as Level 2 of the fair value hierarchy.

Mortgage-related and asset-backed securities are usually issued as separate tranches, or classes, of securities within each deal. These securities are also normally valued by Pricing Sources that use broker-dealer quotations, reported trades or valuation estimates from their internal pricing models.

The pricing models for these securities usually consider tranche-level attributes, current market data, estimated cash flows and market-based yield spreads for each tranche, and incorporate deal collateral performance, as available. Mortgage-related and asset-backed securities that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Valuation adjustments may be applied to certain securities that are solely traded on a foreign exchange to account for the market movement between the close of the foreign market and the NYSE Close. These securities are valued using Pricing Sources that consider the correlation of the trading patterns of the foreign security to the intraday trading in the U.S. markets for investments. Securities using these valuation adjustments are categorized as Level 2 of the fair value hierarchy. Preferred securities and other equities traded on inactive markets or valued by reference to similar instruments are also categorized as Level 2 of the fair value hierarchy.

Valuation adjustments may be applied to certain exchange traded futures and options to account for market movement between the exchange settlement and the NYSE close. These securities are valued using quotes obtained from a quotation reporting system, established market makers or Pricing Sources. Financial derivatives using these valuation adjustments are categorized as Level 2 of the fair value hierarchy.

Equity exchange-traded options and over the counter financial derivative instruments, such as forward foreign currency contracts and options contracts derive their value from underlying asset prices, indices, reference rates, and other inputs or a combination of these factors. These contracts are normally valued on the basis of quotes obtained from a quotation reporting system, established market makers or Pricing Sources (normally determined as of the NYSE Close). Depending on the product and the terms of the transaction, financial derivative instruments can be valued by Pricing Sources using a series of techniques, including simulation pricing models. The pricing models use inputs that are observed from actively quoted markets such as quoted prices, issuer details, indices, bid/ask spreads, interest rates, implied volatilities, yield curves, dividends and exchange rates. Financial derivative instruments that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Centrally cleared swaps and over the counter swaps derive their value from underlying asset prices, indices, reference rates, and other inputs or a combination of these factors. They are valued using a broker-dealer bid quotation or on market-based prices provided by Pricing Sources (normally determined as of the NYSE Close). Centrally cleared swaps and over the counter swaps can be valued by Pricing Sources using a series of techniques, including simulation pricing models. The pricing models may use inputs that are observed from actively quoted markets such as the overnight index swap rate, LIBOR forward rate, interest rates, yield curves and credit spreads. These securities are categorized as Level 2 of the fair value hierarchy.

Short-term debt instruments (such as commercial paper) having a remaining maturity of 60 days or less may be valued at amortized cost, so long as the amortized cost value of such short-term debt instruments is approximately the same as the fair value of the instrument as determined without the use of amortized cost valuation. These securities are categorized as Level 2 or Level 3 of the fair value hierarchy depending on the source of the base price.

Notes to Financial Statements (Cont.)

When a fair valuation method is applied by PIMCO that uses significant unobservable inputs, investments will be priced by a method that the Valuation Designee believes reflects fair value and are categorized as Level 3 of the fair value hierarchy.

(b) Investments in Securities

The Portfolios may utilize the investments and strategies described below to the extent permitted by each Portfolio’s respective investment policies.

104 PIMCO MANAGED ACCOUNTS TRUST

(Unaudited)

June 30, 2023

Delayed-Delivery Transactions  involve a commitment by a Portfolio to purchase or sell securities for a predetermined price or yield, with payment and delivery taking place beyond the customary settlement period. When delayed-delivery transactions are outstanding, a Portfolio will designate or receive as collateral liquid assets in an amount sufficient to meet the purchase price or respective obligations. When purchasing a security on a delayed-delivery basis, a Portfolio assumes the rights and risks of ownership of the security, including the risk of price and yield fluctuations, and takes such fluctuations into account when determining its NAV. A Portfolio may dispose of or renegotiate a delayed-delivery transaction after it is entered into, which may result in a realized gain (loss). When a Portfolio has sold a security on a delayed-delivery basis, the Portfolio does not participate in future gains (losses) with respect to the security.

Inflation-Indexed Bonds  are fixed income securities whose principal value is periodically adjusted to the rate of inflation. In general, the value of an inflation-indexed security tends to decrease when real interest rates increase and can increase when real interest rates decrease. Thus generally, during periods of rising inflation, the value of inflation-indexed securities will tend to increase and during periods of deflation, their value will tend to decrease. The interest rate on these bonds is generally fixed at issuance at a rate lower than typical bonds. Over the life of an inflation-indexed bond, however, interest will be paid based on a principal value which is adjusted for inflation. Any increase or decrease in the principal amount of an inflation-indexed bond will be included as interest income on the Statements of Operations, even though investors do not receive their principal until maturity. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal.

Loans and Other Indebtedness, Loan Participations and Assignments  are direct debt instruments which are interests in amounts owed to lenders or lending syndicates by corporate, governmental, or other borrowers. A Portfolio’s investments in loans may be in the form of direct investments, participations in loans or assignments of all or a portion of loans from third parties or exposure to investments in loans through investments in a mutual fund or other pooled investment vehicle. A loan is often administered by a bank or other financial institution (the “agent”) that acts as agent for all holders. The agent administers the terms of the loan, as specified in the loan agreement. A Portfolio may invest in multiple series or tranches of a loan, which may have varying terms and carry different associated risks. A Portfolio generally has no right to enforce compliance with the terms of the loan agreement with the borrower. As a result, a Portfolio may be subject to the credit risk of both the borrower and the agent that is selling the loan agreement.

In the event of the insolvency of the agent selling a participation, a Portfolio may be treated as a general creditor of the agent and may not benefit from any set-off between the agent and the borrower. When a Portfolio purchases assignments from agents it acquires direct rights against the borrowers of the loans. These loans may include participations in bridge loans, which are loans taken out by borrowers for a short period (typically less than one year) pending arrangement of more permanent financing through, for example, the issuance of bonds, frequently high yield bonds issued for the purpose of acquisitions.

Investments in loans are generally subject to risks similar to those of investments in other types of debt obligations, including, among others, credit risk, interest rate risk, variable and floating rate

SEMIANNUAL REPORT JUNE 30, 2023 105

Notes to Financial Statements (Cont.)

securities risk, and risks associated with mortgage-related securities. In addition, in many cases loans are subject to the risks associated with below-investment grade securities. The Portfolios may be subject to heightened or additional risks and potential liabilities and costs by investing in mezzanine and other subordinated loans, including those arising under bankruptcy, fraudulent conveyance, equitable subordination, environmental and other laws and regulations, and risks and costs associated with debt servicing and taking foreclosure actions associated with the loans.

Additionally, because loans are not ordinarily registered with the SEC or any state securities commission or listed on any securities exchange, there is usually less publicly available information about such instruments. In addition, loans may not be considered “securities” for purposes of the anti-fraud provisions under the federal securities laws and, as a result, as a purchaser of these instruments, a Portfolio may not be entitled to the anti-fraud protections of the federal securities laws. In the course of investing in such instruments, a Portfolio may come into possession of material nonpublic information and, because of prohibitions on trading in securities of issuers while in possession of such information, the Portfolio may be unable to enter into a transaction in a publicly-traded security of that issuer when it would otherwise be advantageous for the Portfolio to do so. Alternatively, a Portfolio may choose not to receive material nonpublic information about an issuer of such loans, with the result that the Portfolio may have less information about such issuers than other investors who transact in such assets.

The types of loans and related investments in which the Portfolios may invest include, among others, senior loans, subordinated loans (including second lien loans, B-Notes and mezzanine loans), whole loans, commercial real estate and other commercial loans and structured loans. The Portfolios may acquire direct interests in loans through primary loan distributions and/or in private transactions. In the case of subordinated loans, there may be significant indebtedness ranking ahead of the borrower’s obligation to the holder of such a loan, including in the event of the borrower’s insolvency. Mezzanine loans are typically secured by a pledge of an equity interest in the mortgage borrower that owns the real estate rather than an interest in a mortgage.

Investments in loans may include unfunded loan commitments, which are contractual obligations for future funding. Unfunded loan commitments may include revolving credit facilities, which may obligate a Portfolio to supply additional cash to the borrower on demand. Unfunded loan commitments represent a future obligation in full, even though a percentage of the committed amount may not be utilized by the borrower. When investing in a loan participation, a Portfolio has the right to receive payments of principal, interest and any fees to which it is entitled only from the agent selling the loan agreement and only upon receipt of payments by the agent from the borrower. Because investing in unfunded loan commitments creates a future obligation for a Portfolio to provide funding to a borrower upon demand in exchange for a fee, the Portfolio will segregate or earmark liquid assets with the Portfolio’s custodian in amounts sufficient to satisfy any such future obligations. A Portfolio may receive a commitment fee based on the undrawn portion of the underlying line of credit portion of a loan. In certain circumstances, a Portfolio may receive a penalty fee upon the prepayment of a loan by a borrower. Fees earned or paid are recorded as a component of interest income or interest expense, respectively, on the Statements of Operations. Unfunded loan commitments, if any, are reflected as a liability on the Statements of Assets and Liabilities.

Mortgage-Related and Other Asset-Backed Securities  directly or indirectly represent a participation in, or are secured by and payable from, loans on real property. Mortgage-related securities are created from pools of residential or commercial mortgage loans, including mortgage loans made by savings and loan institutions, mortgage bankers, commercial banks and others. These securities provide a monthly payment which consists of both interest and principal. Interest may be determined by fixed or adjustable rates. The rate of prepayments on underlying mortgages will affect the price and volatility of a mortgage-related security, and may have the effect of shortening or extending the effective duration of the security relative to what was anticipated at the time of purchase. The timely payment of principal and interest of certain mortgage-related securities is guaranteed with the full faith and credit of the U.S. Government. Pools created and guaranteed by non-governmental issuers, including government-sponsored corporations, may be supported by various forms of insurance or guarantees, but there can be no assurance that private insurers or guarantors can meet their obligations under the insurance policies or guarantee arrangements. Many of the risks of investing in mortgage-related securities secured by commercial mortgage loans reflect the effects of local and other economic conditions on real estate markets, the ability of tenants to make lease payments, and the ability of a property to attract and retain tenants. These securities may be less liquid and may exhibit greater price volatility than other types of mortgage-related or other asset-backed securities. Other asset-backed securities are created from many types of assets, including, but not limited to, auto loans, accounts receivable, such as credit card receivables and hospital account receivables, home equity loans, student loans, boat loans, mobile home loans, recreational vehicle loans, manufactured housing loans, aircraft leases, computer leases and syndicated bank loans.

Collateralized Debt Obligations  (“CDOs”) include Collateralized Bond Obligations (“CBOs”), Collateralized Loan Obligations (“CLOs”) and other similarly structured securities. CBOs and CLOs are types of asset-backed securities. A CBO is a trust which is backed by a diversified pool of high risk, below investment grade fixed income securities. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. For both CBOs and CLOs, the cash flows from the trust are split into two or more portions, called tranches, varying in risk and yield. The riskiest portion is the “equity” tranche which bears the bulk of defaults from the bonds or loans in the trust and serves to protect the other, more senior tranches from default in all but the most severe circumstances. Since it is partially protected from defaults, a senior tranche from a CBO trust or CLO trust typically has higher ratings and lower yields than the underlying securities, and can be rated investment grade. Despite the protection from the equity tranche, CBO or CLO tranches can experience substantial losses due to actual defaults, increased sensitivity to defaults due to collateral default and disappearance of protecting tranches, market anticipation of defaults and aversion to CBO or CLO securities as a class. The risks of an investment in a CDO depend largely on the type of the collateral securities and the class of the CDO in which a Portfolio invests. CDOs carry additional risks including, but not limited to, (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments, (ii) the collateral may decline in value or default, (iii) the risk that a Portfolio may invest in CDOs that are subordinate to other classes, and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.

SEMIANNUAL REPORT JUNE 30, 2023 107

Notes to Financial Statements (Cont.)

Collateralized Mortgage Obligations  (“CMOs”) are debt obligations of a legal entity that are collateralized by whole mortgage loans or private mortgage bonds and divided into classes. CMOs are structured into multiple classes, often referred to as “tranches,” with each class bearing a different stated maturity and entitled to a different schedule for payments of principal and interest, including prepayments. CMOs may be less liquid and may exhibit greater price volatility than other types of mortgage-related or asset-backed securities.

As CMOs have evolved, some classes of CMO bonds have become more common. For example, a Portfolio may invest in parallel-pay and planned amortization class (“PAC”) CMOs and multi-class pass-through certificates. Parallel-pay CMOs and multi-class pass-through certificates are structured to provide payments of principal on each payment date to more than one class. These simultaneous payments are taken into account in calculating the stated maturity date or final distribution date of each class, which, as with other CMO and multi-class pass-through structures, must be retired by its stated maturity date or final distribution date but may be retired earlier. PACs generally require payments of a specified amount of principal on each payment date. PACs are parallel-pay CMOs with the required principal amount on such securities having the highest priority after interest has been paid to all classes. Any CMO or multi-class pass-through structure that includes PAC securities must also have support tranches — known as support bonds, companion bonds or non-PAC bonds — which lend or absorb principal cash flows to allow the PAC securities to maintain their stated maturities and final distribution dates within a range of actual prepayment experience. These support tranches are subject to a higher level of maturity risk compared to other mortgage-related securities, and usually provide a higher yield to compensate investors. If principal cash flows are received in amounts outside a pre-determined range such that the support bonds cannot lend or absorb sufficient cash flows to the PAC securities as intended, the PAC securities are subject to heightened maturity risk. A Portfolio may invest in various tranches of CMO bonds, including support bonds and equity or “first loss” tranches (see “Collateralized Debt Obligations” above).

Perpetual Bonds  are fixed income securities with no maturity date but pay a coupon in perpetuity (with no specified ending or maturity date). Unlike typical fixed income securities, there is no obligation for perpetual bonds to repay principal. The coupon payments, however, are mandatory. While perpetual bonds have no maturity date, they may have a callable date in which the perpetuity is eliminated and the issuer may return the principal received on the specified call date. Additionally, a perpetual bond may have additional features, such as interest rate increases at periodic dates or an increase as of a predetermined point in the future.

Restricted Investments  are subject to legal or contractual restrictions on resale and may generally be sold privately, but may be required to be registered or exempted from such registration before being sold to the public. Private placement securities are generally considered to be restricted except for those securities traded between qualified institutional investors under the provisions of Rule 144A of the Securities Act of 1933. Disposal of restricted investments may involve time-consuming negotiations and expenses, and prompt sale at an acceptable price may be difficult to achieve. Restricted investments held by the Portfolios as of June 30, 2023, as applicable, are disclosed in the Notes to Schedules of Investments.

Securities Issued by U.S. Government Agencies or Government-Sponsored Enterprises  are obligations of and, in certain cases, guaranteed by, the U.S. Government, its agencies or

instrumentalities. Some U.S. Government securities, such as Treasury bills, notes and bonds, and securities guaranteed by the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Government; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the U.S. Department of the Treasury (the “U.S. Treasury”); and others, such as those of the Federal National Mortgage Association (“FNMA” or “Fannie Mae”), are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations. U.S. Government securities may include zero coupon securities which do not distribute interest on a current basis and tend to be subject to a greater risk than interest-paying securities of similar maturities.

Government-related guarantors (i.e., not backed by the full faith and credit of the U.S. Government) include FNMA and the Federal Home Loan Mortgage Corporation (“FHLMC” or “Freddie Mac”). FNMA is a government-sponsored corporation. FNMA purchases conventional (i.e., not insured or guaranteed by any government agency) residential mortgages from a list of approved seller/servicers which include state and federally chartered savings and loan associations, mutual savings banks, commercial banks and credit unions and mortgage bankers. Pass-through securities issued by FNMA are guaranteed as to timely payment of principal and interest by FNMA, but are not backed by the full faith and credit of the U.S. Government. FHLMC issues Participation Certificates (“PCs”), which are pass-through securities, each representing an undivided interest in a pool of residential mortgages. FHLMC guarantees the timely payment of interest and ultimate collection of principal, but PCs are not backed by the full faith and credit of the U.S. Government. Instead, they are supported only by the discretionary authority of the U.S. Government to purchase the agency’s obligations.

In June 2019, FNMA and FHLMC started issuing Uniform Mortgage Backed Securities in place of their current offerings of TBA-eligible securities (the “Single Security Initiative”). The Single Security Initiative seeks to support the overall liquidity of the TBA market and aligns the characteristics of FNMA and FHLMC certificates. The long-term effects that the Single Security Initiative may have on the market for TBA and other mortgage-backed securities are uncertain.

Roll-timing strategies can be used where a Portfolio seeks to extend the expiration or maturity of a position, such as a TBA security on an underlying asset, by closing out the position before expiration and opening a new position with respect to substantially the same underlying asset with a later expiration date. TBA securities purchased or sold are reflected on the Statements of Assets and Liabilities as an asset or liability, respectively. Recently finalized FINRA rules include mandatory margin requirements for the TBA market that require the Portfolios to post collateral in connection with their TBA transactions. There is no similar requirement applicable to the Portfolios’ TBA counterparties. The required collateralization of TBA trades could increase the cost of TBA transactions to the Portfolios and impose added operational complexity.

When-Issued Transactions are purchases or sales made on a when-issued basis. These transactions are made conditionally because a security, although authorized, has not yet been issued in the market. Transactions to purchase or sell securities on a when-issued basis involve a commitment by a Portfolio to purchase or sell these securities for a predetermined price or yield, with payment and delivery taking place beyond the customary settlement period. When purchasing a security on a delayed delivery basis, a Portfolio assumes the rights and risks of ownership of the security, including

SEMIANNUAL REPORT JUNE 30, 2023 109

Notes to Financial Statements (Cont.)

the risk of price and yield fluctuations. A Portfolio may sell when-issued securities before they are delivered, which may result in a realized gain (loss).

5. BORROWINGS AND OTHER FINANCING TRANSACTIONS

The Portfolios may enter into the borrowings and other financing transactions described below to the extent permitted by each Portfolio’s respective investment policies.

The following disclosures contain information on a Portfolio’s ability to lend or borrow cash or securities to the extent permitted under the Act, which may be viewed as borrowing or financing transactions by a Portfolio. The location of these instruments in each Portfolio’s financial statements is described below.

(a) Repurchase Agreements  Under the terms of a typical repurchase agreement, a Portfolio purchases an underlying debt obligation (collateral) subject to an obligation of the seller to repurchase, and a Portfolio to resell, the obligation at an agreed-upon price and time. In an open maturity repurchase agreement, there is no pre-determined repurchase date and the agreement can be terminated by the Portfolio or counterparty at any time. The underlying securities for all repurchase agreements are held by a Portfolio’s custodian or designated subcustodians (in the case of tri-party repurchase agreements) and in certain instances will remain in custody with the counterparty. Traditionally, a Portfolio has used bilateral repurchase agreements wherein the underlying securities will be held by a Portfolio’s custodian. The market value of the collateral must be equal to or exceed the total amount of the repurchase obligations, including interest. Repurchase agreements, if any, including accrued interest, are included on the Statements of Assets and Liabilities. Interest earned is recorded as a component of interest income on the Statements of Operations. In periods of increased demand for collateral, a Portfolio may pay a fee for the receipt of collateral, which may result in interest expense to the Portfolio.

(b) Reverse Repurchase Agreements  In a reverse repurchase agreement, a Portfolio delivers a security in exchange for cash to a financial institution, the counterparty, with a simultaneous agreement to repurchase the same or substantially the same security at an agreed upon price and date. In an open maturity reverse repurchase agreement, there is no pre-determined repurchase date and the agreement can be terminated by a Portfolio or counterparty at any time. A Portfolio is entitled to receive principal and interest payments, if any, made on the security delivered to the counterparty during the term of the agreement. Cash received in exchange for securities delivered plus accrued interest payments to be made by a Portfolio to counterparties are reflected as a liability on the Statements of Assets and Liabilities. Interest payments made by a Portfolio to counterparties are recorded as a component of interest expense on the Statements of Operations. In periods of increased demand for the security, a Portfolio may receive a fee for use of the security by the counterparty, which may result in interest income to the Portfolio. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, a Portfolio’s use of the proceeds of the agreement may be restricted pending a determination by the other party, or its trustee or receiver, whether to enforce a Portfolio’s obligation to repurchase the securities. Reverse repurchase agreements involve leverage risk and also the risk that the market value of the securities to be repurchased may decline below the repurchase price. A Portfolio will segregate assets determined to be liquid by PIMCO or will otherwise cover its obligations under reverse repurchase agreements.

(c) Sale-Buybacks  A sale-buyback financing transaction consists of a sale of a security by a Portfolio to a financial institution, the counterparty, with a simultaneous agreement to repurchase the same or substantially the same security at an agreed-upon price and date. A Portfolio is not entitled to receive principal and interest payments, if any, made on the security sold to the counterparty during the term of the agreement. The agreed-upon proceeds for securities to be repurchased by a Portfolio are reflected as a liability on the Statements of Assets and Liabilities. A Portfolio will recognize net income represented by the price differential between the price received for the transferred security and the agreed-upon repurchase price. This is commonly referred to as the ‘price drop’. A price drop consists of (i) the foregone interest and inflationary income adjustments, if any, a Portfolio would have otherwise received had the security not been sold and (ii) the negotiated financing terms between a Portfolio and counterparty. Foregone interest and inflationary income adjustments, if any, are recorded as components of interest income on the Statements of Operations. Interest payments based upon negotiated financing terms made by a Portfolio to counterparties are recorded as a component of interest expense on the Statements of Operations. In periods of increased demand for the security, a Portfolio may receive a fee for use of the security by the counterparty, which may result in interest income to the Portfolio. A Portfolio will segregate assets determined to be liquid by PIMCO or will otherwise cover its obligations under sale-buyback transactions. Sale-buybacks involve leverage risk and also the risk that the market value of the securities to be repurchased may decline below the repurchase price.

(d) Short Sales  Short sales are transactions in which a Portfolio sells a security that it may not own. A Portfolio may make short sales of securities to (i) offset potential declines in long positions in similar securities, (ii) to increase the flexibility of the Portfolio, (iii) for investment return, (iv) as part of a risk arbitrage strategy, and (v) as part of its overall portfolio management strategies involving the use of derivative instruments. When a Portfolio engages in a short sale, it may borrow the security sold short and deliver it to the counterparty. A Portfolio will ordinarily have to pay a fee or premium to borrow a security and be obligated to repay the lender of the security any dividend or interest that accrues on the security during the period of the loan. Securities sold in short sale transactions and the dividend or interest payable on such securities, if any, are reflected as payable for short sales on the Statements of Assets and Liabilities. Short sales expose a Portfolio to the risk that it will be required to cover its short position at a time when the security or other asset has appreciated in value, thus resulting in losses to a Portfolio. A short sale is “against the box” if a Portfolio holds in its portfolio or has the right to acquire the security sold short, or securities identical to the security sold short, at no additional cost. A Portfolio will be subject to additional risks to the extent that it engages in short sales that are not “against the box.” A Portfolio’s loss on a short sale could theoretically be unlimited in cases where a Portfolio is unable, for whatever reason, to close out its short position.

(e) Tender Option Bond Transactions  In a tender option bond transaction (“TOB”), a tender option bond trust (“TOB Trust”) issues floating rate certificates (“TOB Floater”) and residual interest certificates (“TOB Residual”) and utilizes the proceeds of such issuances to purchase a fixed rate municipal bond (“Fixed Rate Bond”) that is either owned or identified by a Portfolio. The TOB Floater is generally issued to third party investors (typically a money market fund) and the TOB Residual is generally issued to the Portfolio that sold or identified the Fixed Rate Bond. The TOB Trust divides the income stream provided by the Fixed Rate Bond to create two securities, the TOB Floater, which

SEMIANNUAL REPORT JUNE 30, 2023 111

Notes to Financial Statements (Cont.)

is a short-term security, and the TOB Residual, which is a longer-term security. The interest rates payable on the TOB Residual issued to a Portfolio bear an inverse relationship to the interest rate on the TOB Floater. The interest rate on the TOB Floater is reset by a remarketing process typically every 7 to 35 days. After income is paid on the TOB Floater at current rates, the residual income from the Fixed Rate Bond goes to the TOB Residual. Therefore, rising short-term rates result in lower income for the TOB Residual, and vice versa. In the case of a TOB Trust that utilizes the cash received (less transaction expenses) from the issuance of the TOB Floater and TOB Residual to purchase the Fixed Rate Bond from the Portfolio, a Portfolio may then invest the cash received in additional securities, generating leverage for the Portfolio. Other PIMCO-managed accounts may also contribute municipal bonds to a TOB Trust into which the Portfolio has contributed Fixed Rate Bonds. If multiple PIMCO-managed accounts participate in the same TOB Trust, the economic rights and obligations under the TOB Residual will be shared among the Portfolios ratably in proportion to their participation in the TOB Trust.

The TOB Residual may be more volatile and less liquid than other municipal bonds of comparable maturity. In most circumstances the TOB Residual holder bears substantially all of the underlying Fixed Rate Bond’s downside investment risk and also benefits from any appreciation in the value of the underlying Fixed Rate Bond. Investments in a TOB Residual typically will involve greater risk than investments in Fixed Rate Bonds.

A TOB Residual held by a Portfolio provides the Portfolio with the right to: (i) cause the holders of the TOB Floater to tender their notes at par, and (ii) cause the sale of the Fixed Rate Bond held by the TOB Trust, thereby collapsing the TOB Trust. TOB Trusts are generally supported by a liquidity facility provided by a third party bank or other financial institution (the “Liquidity Provider”) that provides for the purchase of TOB Floaters that cannot be remarketed. The holders of the TOB Floaters have the right to tender their certificates in exchange for payment of par plus accrued interest on a periodic basis (typically weekly) or on the occurrence of certain mandatory tender events. The tendered TOB Floaters are remarketed by a remarketing agent, which is typically an affiliated entity of the Liquidity Provider. If the TOB Floaters cannot be remarketed, the TOB Floaters are purchased by the TOB Trust either from the proceeds of a loan from the Liquidity Provider or from a liquidation of the Fixed Rate Bond.

The TOB Trust may also be collapsed without the consent of a Portfolio, as the TOB Residual holder, upon the occurrence of certain “tender option termination events” (or “TOTEs”) as defined in the TOB Trust agreements. Such termination events typically include the bankruptcy or default of the Fixed Rate Bond, a substantial downgrade in credit quality of the Fixed Rate Bond, or a judgment or ruling that interest on the Fixed Rate Bond is subject to Federal income taxation. Upon the occurrence of a termination event, the TOB Trust would generally be liquidated in full with the proceeds typically applied first to any accrued fees owed to the trustee, remarketing agent and liquidity provider, and then to the holders of the TOB Floater up to par plus accrued interest owed on the TOB Floater and a portion of gain share, if any, with the balance paid out to the TOB Residual holder. In the case of a mandatory termination event (“MTE”), after the payment of fees, the TOB Floater holders would be paid before the TOB Residual holders (i.e., the Portfolios). In contrast, in the case of a TOTE, after payment of fees, the TOB Floater holders and the TOB Residual holders would be paid pro rata in proportion to the respective face values of their certificates.

If there are insufficient proceeds from the liquidation of the TOB Trust, the party that would bear the losses would depend upon whether a Portfolio holds a non-recourse TOBs Residual or a recourse TOBs Residual. If a Portfolio holds a non-recourse TOBs Residual, the Liquidity Provider or holders of the TOBs Floaters would bear the losses on those securities and there would be no recourse to the Portfolio’s assets. If a Portfolio holds a recourse TOBs Residual, the Portfolio (and, indirectly, holders of the Portfolio’s common shares) would typically bear the losses. In particular, if a Portfolio holds a recourse TOBs Residual, it will typically have entered into an agreement pursuant to which the Portfolio would be required to pay to the Liquidity Provider the difference between the purchase price of any TOBs Floaters put to the Liquidity Provider by holders of the TOBs Floaters and the proceeds realized from the remarketing of those TOBs Floaters or the sale of the assets in the TOBs Issuer. A Portfolio may invest in both non-recourse and recourse TOBs Residuals to leverage its portfolio.

Each Portfolio’s transfer of Fixed Rate Bonds to a TOB Trust is considered a secured borrowing for financial reporting purposes. The cash received by the TOB Trust from the sale of the TOB Floaters, less certain transaction expenses, is paid to a Portfolio. A Portfolio typically invests the cash received in additional municipal bonds. The Portfolios account for the transactions described above as secured borrowings by including the Fixed Rate Bonds in their Schedules of Investments, and account for the TOB Floater as a liability under the caption “Payable for tender option bond floating rate certificates” in the Portfolios’ Statements of Assets and Liabilities. Interest income, including amortization and accretion of premiums and discounts, from the underlying municipal bonds is recorded by each Portfolio on an accrual basis and is shown as interest on the Statements of Operations. Interest expense incurred on the secured borrowing is shown as interest expense on the Statements of Operations.

The Portfolios may also purchase TOB Residuals in a secondary market transaction without transferring a fixed rate municipal bond into a TOB Trust. Such transactions are not accounted for as secured borrowings but rather as a security purchase with the TOB Residual being included in the Schedule of Investments.

In December 2013, regulators finalized rules implementing Section 619 (the “Volcker Rule”) and Section 941 (the “Risk Retention Rules”) of the Dodd-Frank Wall Street Reform and Consumer Protection Act. Both the Volcker Rule and the Risk Retention Rules apply to tender option bond programs. The Volcker Rule precludes banking entities from (i) sponsoring or acquiring interests in the trusts used to hold a municipal bond in the creation of TOB Trusts; and (ii) continuing to service or maintain relationships with existing programs involving TOB Trusts to the same extent and in the same capacity as existing programs. The Risk Retention Rules require the sponsor to a TOB Trust (e.g., a Portfolio) to retain at least five percent of the credit risk of the underlying assets supporting the TOB Trust’s municipal bonds. The Risk Retention Rules may adversely affect the Portfolio’s ability to engage in tender option bond trust transactions or increase the costs of such transactions in certain circumstances.

In response to these rules, industry participants explored various structuring alternatives for TOB Trusts established after December 31, 2013 and TOB Trusts established prior to December 31, 2013 (“Legacy TOB Trusts”) and agreed on a new tender option bond structure in which the Portfolios hire service providers to assist with establishing, structuring and sponsoring a TOB Trust.

providers to a TOB Trust, such as administrators, liquidity providers, trustees and remarketing agents act at the direction of, and as agent of, the Portfolios as the TOB residual holders.

The Portfolios have restructured their Legacy TOB Trusts in conformity with regulatory guidelines. Under the new TOB Trust structure, the Liquidity Provider or remarketing agent will no longer purchase the tendered TOB Floaters, even in the event of failed remarketing. This may increase the likelihood that a TOB Trust will need to be collapsed and liquidated in order to purchase the tendered TOB Floaters. The TOB Trust may draw upon a loan from the Liquidity Provider to purchase the tendered TOB Floaters. Any loans made by the Liquidity Provider will be secured by the purchased TOB Floaters held by the TOB Trust and will be subject to an interest rate agreed upon with the liquidity provider.

For the period ended June 30, 2023, the Portfolios’ average leverage outstanding from the use of TOB transactions and the daily weighted average interest rate, including fees, were as follows:

Portfolio Name	Average Leverage Outstanding (000s)		Weighted Average Interest Rate*
Fixed Income SHares - Series TE	$	2,291		3.48%

* Annualized

(f) Interfund Lending  In accordance with an exemptive order (the “Order”) from the SEC, the Portfolios of the Trust may participate in a joint lending and borrowing facility for temporary purposes (the “Interfund Lending Program”), subject to compliance with the terms and conditions of the Order, and to the extent permitted by each Portfolio’s investment policies and restrictions. The Portfolios are currently permitted to borrow under the Interfund Lending Program. A lending portfolio may lend in aggregate up to 15% of its current net assets at the time of the interfund loan, but may not lend more than 5% of its net assets to any one borrowing portfolio through the Interfund Lending Program. A borrowing portfolio may not borrow through the Interfund Lending Program or from any other source if its total outstanding borrowings immediately after the borrowing would be more than 33 1/3% of its total assets (or any lower threshold provided for by the portfolio’s investment restrictions). If a borrowing portfolio’s total outstanding borrowings exceed 10% of its total assets, each of its outstanding interfund loans will be subject to collateralization of at least 102% of the outstanding principal value of the loan. All interfund loans are for temporary or emergency purposes and the interfund loan rate to be charged will be the average of the highest current overnight repurchase agreement rate available to a lending portfolio and the bank loan rate, as calculated according to a formula established by the Board.

During the period ended June 30, 2023, the Portfolios did not participate in the Interfund Lending Program.

6. FINANCIAL DERIVATIVE INSTRUMENTS

The Portfolios may enter into the financial derivative instruments described below to the extent permitted by each Portfolio’s respective investment policies.

The following disclosures contain information on how and why the Portfolios use financial derivative instruments, and how financial derivative instruments affect the Portfolios’ financial position, results

of operations and cash flows. The location and fair value amounts of these instruments on the Statements of Assets and Liabilities and the net realized gain (loss) and net change in unrealized appreciation (depreciation) on the Statements of Operations, each categorized by type of financial derivative contract and related risk exposure, are included in a table in the Notes to Schedules of Investments. The financial derivative instruments outstanding as of period end and the amounts of net realized gain (loss) and net change in unrealized appreciation (depreciation) on financial derivative instruments during the period, as disclosed in the Notes to Schedules of Investments, serve as indicators of the volume of financial derivative activity for the Portfolios.

(a) Forward Foreign Currency Contracts  may be engaged, in connection with settling planned purchases or sales of securities, to hedge the currency exposure associated with some or all of a Portfolio’s securities or as part of an investment strategy. A forward foreign currency contract is an agreement between two parties to buy and sell a currency at a set price on a future date. The market value of a forward foreign currency contract fluctuates with changes in foreign currency exchange rates. Forward foreign currency contracts are marked to market daily, and the change in value is recorded by a Portfolio as an unrealized gain (loss). Realized gains (losses) are equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed and are recorded upon delivery or receipt of the currency. The contractual obligations of a buyer or seller of a forward foreign currency contract may generally be satisfied by taking or making physical delivery of the underlying currency, establishing an opposite position in the contract and recognizing the profit or loss on both positions simultaneously on the delivery date or, in some instances, paying a cash settlement before the designated date of delivery. These contracts may involve market risk in excess of the unrealized gain (loss) reflected on the Statements of Assets and Liabilities. Although forwards may be intended to minimize the risk of loss due to a decline in the value of the hedged currencies, at the same time, they tend to limit any potential gain which might result should the value of such currencies increase. In addition, a Portfolio could be exposed to risk if the counterparties are unable to meet the terms of the contracts or if the value of the currency changes unfavorably to the U.S. dollar. To mitigate such risk, cash or securities may be exchanged as collateral pursuant to the terms of the underlying contracts.

(b) Futures Contracts  are agreements to buy or sell a security or other asset for a set price on a future date and are traded on an exchange. A Portfolio may use futures contracts to manage its exposure to the securities markets or to movements in interest rates and currency values. The primary risks associated with the use of futures contracts are the imperfect correlation between the change in market value of the securities held by a Portfolio and the prices of futures contracts and the possibility of an illiquid market. Futures contracts are valued based upon their quoted daily settlement prices. Upon entering into a futures contract, a Portfolio is required to deposit with its futures broker an amount of cash, U.S. Government and Agency Obligations, or select sovereign debt, in accordance with the initial margin requirements of the broker or exchange. Futures contracts are marked to market daily and based on such movements in the price of the contracts, an appropriate payable or receivable for the change in value may be posted or collected by a Portfolio (“Futures Variation Margin”). Futures Variation Margins, if any, are disclosed within centrally cleared financial derivative instruments on the Statements of Assets and Liabilities. Gains (losses) are recognized but not considered realized until the contracts expire or close. Futures contracts involve, to varying degrees, risk of loss in excess of the Futures Variation Margin included within exchange traded or centrally cleared financial derivative instruments on the Statements of Assets and Liabilities.

(c) Options Contracts  An option on an instrument (or an index) is a contract that gives the holder of the option, in return for a premium, the right to buy from (in the case of a call) or sell to (in the case of a put) the writer of the option the instrument underlying the option (or the cash value of the index) at a specified exercise price at any time during the term of the option. Writing put options tends to increase a Portfolio’s exposure to the underlying instrument. Writing call options tends to decrease a Portfolio’s exposure to the underlying instrument. When a Portfolio writes a call or put, an amount equal to the premium received is recorded and subsequently marked to market to reflect the current value of the option written. These amounts are included on the Statements of Assets and Liabilities. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or closed are added to the proceeds or offset against amounts paid on the underlying futures, swap, security or currency transaction to determine the realized gain (loss). Certain options may be written with premiums to be determined on a future date. The premiums for these options are based upon implied volatility parameters at specified terms. A Portfolio as a writer of an option has no control over whether the underlying instrument may be sold (“call”) or purchased (“put”) and as a result bears the market risk of an unfavorable change in the price of the instrument underlying the written option. There is the risk a Portfolio may not be able to enter into a closing transaction because of an illiquid market.

Purchasing call options tends to increase a Portfolio’s exposure to the underlying instrument. Purchasing put options tends to decrease a Portfolio’s exposure to the underlying instrument. A Portfolio pays a premium which is included as an asset on the Statements of Assets and Liabilities and subsequently marked to market to reflect the current value of the option. Premiums paid for purchasing options which expire are treated as realized losses. Certain options may be purchased with premiums to be determined on a future date. The premiums for these options are based upon implied volatility parameters at specified terms. The risk associated with purchasing put and call options is limited to the premium paid. Premiums paid for purchasing options which are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying investment transaction to determine the realized gain (loss) when the underlying transaction is executed.

Inflation-Capped Options  may be written or purchased to enhance returns or for hedging opportunities. The purpose of purchasing inflation-capped options is to protect a Portfolio from inflation erosion above a certain rate on a given notional exposure. A floor can be used to give downside protection to investments in inflation-linked products.

Interest Rate Swaptions  may be written or purchased to enter into a pre-defined swap agreement or to shorten, extend, cancel or otherwise modify an existing swap agreement, by some specified date in the future. The writer of the swaption becomes the counterparty to the swap if the buyer exercises. The interest rate swaption agreement will specify whether the buyer of the swaption will be a fixed-rate receiver or a fixed-rate payer upon exercise.

Options on Exchange-Traded Futures Contracts  (“Futures Option”) may be written or purchased to hedge an existing position or future investment, for speculative purposes or to manage exposure to market movements. A Futures Option is an option contract in which the underlying instrument is a single futures contract.

(d) Swap Agreementsare bilaterally negotiated agreements between a Portfolio and a counterparty to exchange or swap investment cash flows, assets, foreign currencies or market-linked returns at specified, future intervals. Swap agreements may be privately negotiated in the over the counter market (“OTC swaps”) or may be cleared through a third party, known as a central counterparty or derivatives clearing organization (“Centrally Cleared Swaps”). A Portfolio may enter into asset, credit default, cross-currency, interest rate, total return, variance and other forms of swap agreements to manage its exposure to credit, currency, interest rate, commodity, equity and inflation risk. In connection with these agreements, securities or cash may be identified as collateral or margin in accordance with the terms of the respective swap agreements to provide assets of value and recourse in the event of default or bankruptcy/insolvency.

Centrally Cleared Swaps are marked to market daily based upon valuations as determined from the underlying contract or in accordance with the requirements of the central counterparty or derivatives clearing organization. Changes in market value, if any, are reflected as a component of net change in unrealized appreciation (depreciation) on the Statements of Operations. Daily changes in valuation of centrally cleared swaps, if any, are recorded as variation margin on the Statements of Assets and Liabilities. Centrally Cleared and OTC swap payments received or paid at the beginning of the measurement period are included on the Statements of Assets and Liabilities and represent premiums paid or received upon entering into the swap agreement to compensate for differences between the stated terms of the swap agreement and prevailing market conditions (credit spreads, currency exchange rates, interest rates, and other relevant factors). Upfront premiums received (paid) are initially recorded as liabilities (assets) and subsequently marked to market to reflect the current value of the swap. These upfront premiums are recorded as realized gain (loss) on the Statements of Operations upon termination or maturity of the swap. A liquidation payment received or made at the termination of the swap is recorded as realized gain (loss) on the Statements of Operations. Net periodic payments received or paid by a Portfolio are included as part of realized gain (loss) on the Statements of Operations.

For purposes of a Portfolio’s investment policy adopted pursuant to Rule 35d-1 under the Act (if any), the Portfolio will account for derivative instruments at market value. For purposes of applying a Portfolio’s other investment policies and restrictions, swap agreements, like other derivative instruments, may be valued by a Portfolio at market value, notional value or full exposure value (i.e., the sum of the notional amount for the contract plus the market value) or any combination of the foregoing (e.g., notional value for purposes of calculating the numerator and market value for purposes of calculating the denominator for compliance with a particular policy or restriction). In the case of a credit default swap, in applying certain of a Portfolio’s investment policies and restrictions, the Portfolios will value the credit default swap at its notional value or its full exposure value (i.e., the sum of the notional amount for the contract plus the market value), but may value the credit default swap at market value for purposes of applying certain of a Portfolio’s other investment policies and restrictions. For example, a Portfolio may value credit default swaps at full exposure value for purposes of a Portfolio’s credit quality guidelines (if any) because such value in general better reflects a Portfolio’s actual economic exposure during the term of the credit default swap agreement. As a result, a Portfolio may, at times, have notional exposure to an asset class (before netting) that is greater or lesser than the stated limit or restriction noted in a Portfolio’s prospectus. In this context, both the notional amount and the market value may be positive or negative depending on whether a Portfolio is selling or buying protection through the credit default swap. The

Notes to Financial Statements (Cont.)

manner in which certain securities or other instruments are valued by a Portfolio for purposes of applying investment policies and restrictions may differ from the manner in which those investments are valued by other types of investors.

Entering into swap agreements involves, to varying degrees, elements of interest, credit, market and documentation risk in excess of the amounts recognized on the Statements of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of contractual terms in the agreements and that there may be unfavorable changes in interest rates or the values of the asset upon which the swap is based.

A Portfolio’s maximum risk of loss from counterparty credit risk is the discounted net value of the cash flows to be received from the counterparty over the contract’s remaining life, to the extent that amount is positive. The risk may be mitigated by having a master netting arrangement between a Portfolio and the counterparty and by the posting of collateral to a Portfolio to cover a Portfolio’s exposure to the counterparty.

To the extent a Portfolio has a policy to limit the net amount owed to or to be received from a single counterparty under existing swap agreements, such limitation only applies to counterparties to OTC swaps and does not apply to centrally cleared swaps where the counterparty is a central counterparty or derivatives clearing organization.

Credit Default Swap Agreements  on corporate, loan, sovereign, U.S. municipal or U.S. Treasury issues are entered into to provide a measure of protection against defaults of the issuers (i.e., to reduce risk where a Portfolio owns or has exposure to the referenced obligation) or to take an active long or short position with respect to the likelihood of a particular issuer’s default. Credit default swap agreements involve one party making a stream of payments (referred to as the buyer of protection) to another party (the seller of protection) in exchange for the right to receive a specified return in the event that the referenced entity, obligation or index, as specified in the swap agreement, undergoes a certain credit event. As a seller of protection on credit default swap agreements, a Portfolio will generally receive from the buyer of protection a fixed rate of income throughout the term of the swap provided that there is no credit event. As the seller, a Portfolio would effectively add leverage to its portfolio because, in addition to its total net assets, a Portfolio would be subject to investment exposure on the notional amount of the swap.

If a Portfolio is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, a Portfolio will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index. If a Portfolio is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, a Portfolio will either (i) receive from the seller of protection an amount equal to the notional amount of the swap and deliver the referenced obligation, other deliverable obligations or underlying securities comprising the referenced index or (ii) receive a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery

value of the referenced obligation or underlying securities comprising the referenced index. Recovery values are estimated by market makers considering either industry standard recovery rates or entity specific factors and considerations until a credit event occurs. If a credit event has occurred, the recovery value is determined by a facilitated auction whereby a minimum number of allowable broker bids, together with a specified valuation method, are used to calculate the settlement value. The ability to deliver other obligations may result in a cheapest-to-deliver option (the buyer of protection’s right to choose the deliverable obligation with the lowest value following a credit event).

Credit default swap agreements on corporate or sovereign issues involve one party making a stream of payments to another party in exchange for the right to receive a specified return in the event of a default or other credit event. If a credit event occurs and cash settlement is not elected, a variety of other deliverable obligations may be delivered in lieu of the specific referenced obligation. The ability to deliver other obligations may result in a cheapest-to-deliver option (the buyer of protection’s right to choose the deliverable obligation with the lowest value following a credit event).

Credit default swap agreements on credit indices involve one party making a stream of payments to another party in exchange for the right to receive a specified return in the event of a write-down, principal shortfall, interest shortfall or default of all or part of the referenced entities comprising the credit index. A credit index is a basket of credit instruments or exposures designed to be representative of some part of the credit market as a whole. These indices are made up of reference credits that are judged by a poll of dealers to be the most liquid entities in the credit default swap market based on the sector of the index. Components of the indices may include, but are not limited to, investment grade securities, high yield securities, asset-backed securities, emerging markets, and/or various credit ratings within each sector. Credit indices are traded using credit default swaps with standardized terms including a fixed spread and standard maturity dates. An index credit default swap references all the names in the index, and if there is a default, the credit event is settled based on that name’s weight in the index. The composition of the indices changes periodically, usually every six months, and for most indices, each name has an equal weight in the index. Credit default swaps on credit indices may be used to hedge a portfolio of credit default swaps or bonds, which is less expensive than it would be to buy many credit default swaps to achieve a similar effect or to take an active long or short position with respect to the likelihood of a particular referenced obligation’s default. Credit default swaps on indices are instruments often used to attempt to protect investors owning bonds against default, but may also be used for speculative purposes.

Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate, loan, sovereign, U.S. municipal or U.S. Treasury issues as of period end, if any, are disclosed in the Notes to Schedules of Investments. They serve as an indicator of the current status of payment/performance risk and represent the likelihood or risk of default for the reference entity. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement. For credit default swap agreements on asset-backed securities and credit indices, the quoted market prices and resulting values serve as the indicator of the current status of the payment/performance risk. Increasing market values, in absolute terms when compared

to the notional amount of the swap, represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

The maximum potential amount of future payments (undiscounted) that a Portfolio as a seller of protection could be required to make under a credit default swap agreement equals the notional amount of the agreement. Notional amounts of each individual credit default swap agreement outstanding as of period end for which a Portfolio is the seller of protection are disclosed in the Notes to Schedules of Investments. These potential amounts would be partially offset by any recovery values of the respective referenced obligations, upfront payments received upon entering into the agreement, or net amounts received from the settlement of buy protection credit default swap agreements entered into by a Portfolio for the same referenced entity or entities.

Interest Rate Swap Agreements  may be entered into to help hedge against interest rate risk exposure and to maintain a Portfolio’s ability to generate income at prevailing market rates. The value of the fixed rate bonds that the Portfolios hold may decrease if interest rates rise. To help hedge against this risk and to maintain its ability to generate income at prevailing market rates, a Portfolio may enter into interest rate swap agreements. Interest rate swap agreements involve the exchange by a Portfolio with another party for their respective commitment to pay or receive interest on the notional amount of principal. Certain forms of interest rate swap agreements may include: (i) interest rate caps, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or ‘‘cap,’’ (ii) interest rate floors, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified rate, or ‘‘floor,’’ (iii) interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels, (iv) callable interest rate swaps, under which the buyer pays an upfront fee in consideration for the right to early terminate the swap transaction in whole, at zero cost and at a predetermined date and time prior to the maturity date, (v) spreadlocks, which allow the interest rate swap users to lock in the forward differential (or spread) between the interest rate swap rate and a specified benchmark, or (vi) basis swaps, under which two parties can exchange variable interest rates based on different segments of money markets.

Please see “Description of Principal Risks” in a Portfolio’s prospectus for a more detailed description of the risks of investing in a Portfolio.

Small Portfolio Risk  is the risk that a smaller portfolio may not achieve investment or trading efficiencies. Additionally, a smaller portfolio may be more adversely affected by large purchases or redemptions of portfolio shares.

Interest Rate Risk  is the risk that fixed income securities will fluctuate in value because of a change in interest rates; a portfolio with a longer average portfolio duration will be more sensitive to changes in interest rates than a portfolio with a shorter average portfolio duration.

Credit Risk  is the risk that a Portfolio could lose money if the issuer or guarantor of a fixed income security (including a security purchased with securities lending collateral), the counterparty to a derivative contract, or the issuer or guarantor of collateral, repurchase agreement or a loan of portfolio securities, is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services or otherwise) as unable or unwilling, to meet its financial obligations. The risk that such issuer, guarantor or counterparty is less willing or able to do so is heightened in market environments where interest rates are rising. Securities are subject to varying degrees of credit risk, which are often reflected in credit ratings.

Market Risk  is the risk that the value of securities owned by a Portfolio may go up or down, sometimes rapidly or unpredictably, due to factors affecting securities markets generally or particular industries or companies.

SEMIANNUAL REPORT JUNE 30, 2023 121

Notes to Financial Statements (Cont.)

Foreign (Non-U.S.) Investment Risk  is the risk that investing in foreign (non-U.S.) securities may result in the Portfolio experiencing more rapid and extreme changes in value than a portfolio that invests exclusively in securities of U.S. issuers or securities that trade exclusively in U.S. markets due to smaller markets, differing reporting, accounting and auditing standards, increased risk of delayed settlement of portfolio transactions or loss of certificates of portfolio securities, and the risk of unfavorable foreign government actions, including nationalization, expropriation or confiscatory taxation, currency blockage, or political changes, diplomatic developments or the imposition of sanctions and other similar measures. Foreign securities may also be less liquid (particularly during market closures due to local holidays or other reasons) and more difficult to value than securities of U.S. issuers.

Mortgage-Related and Other Asset-Backed Securities Risk  is the risk of investing in mortgage- related and other asset-backed securities, including interest rate risk, extension risk, prepayment risk and credit risk.

Emerging Markets Risk  is the risk of investing in emerging market securities, primarily increased foreign (non-U.S.) investment risk.

Focused Investment Risk  is the risk that, to the extent that the Portfolio focuses its investments in a particular sector, it may be susceptible to loss due to adverse developments affecting that sector. Furthermore, the Portfolio may invest a substantial portion of its assets in companies in related sectors that may share common characteristics, are often subject to similar business risks and regulatory burdens, and whose securities may react similarly to market developments, which will subject the Portfolio to greater risk. The Portfolio also will be subject to focused investment risk to the extent that it invests a substantial portion of its assets in a particular issuer, market, asset class, country or geographic region.

Derivatives Risk  is the risk of investing in derivative instruments (such as forwards, futures, swaps and structured securities) and other similar investments, including leverage, liquidity, interest rate, market, counterparty (including credit), operational, legal and management risks and valuation complexity. Changes in the value of a derivative or other similar investment may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and the Portfolio could lose more than the initial amount invested. Changes in the value of a derivative or other similar instrument may also create margin delivery or settlement payment obligations for the Portfolio. The Portfolio’s use of derivatives or other similar investments may result in losses to the Portfolio, a reduction in the Portfolio’s returns and/or increased volatility. Over- the-counter (“OTC”) derivatives or other similar investments are also subject to the risk that a counterparty to the transaction will not fulfill its contractual obligations to the other party, as many of the protections afforded to centrally-cleared derivative transactions might not be available for OTC derivatives or other similar investments. The primary credit risk on derivatives that are exchange- traded or traded through a central clearing counterparty, resides with the Portfolio’s clearing broker or the clearinghouse. Changes in regulation relating to a registered fund’s use of derivatives and related instruments could potentially limit or impact the Portfolio’s ability to invest in derivatives, limit the Portfolio’s ability to employ certain strategies that use derivatives or other similar investments and/or adversely affect the value of derivatives or other similar investments and the Portfolio’s performance.

Liquidity Risk  is the risk that a particular investment may be difficult to purchase or sell and that the Portfolio may be unable to sell illiquid investments at an advantageous time or price or achieve its desired level of exposure to a certain sector. Liquidity risk may result from the lack of an active market, reduced number and capacity of traditional market participants to make a market in fixed income securities, and may be magnified in a rising interest rate environment or other circumstances where investor redemptions from fixed income funds may be higher than normal, causing increased supply in the market due to selling activity.

Management Risk  is the risk that the investment techniques and risk analyses applied by PIMCO will not produce the desired results and that actual or potential conflicts of interest, legislative, regulatory, or tax restrictions, policies or developments may affect the investment techniques available to PIMCO and the individual portfolio managers in connection with managing the Portfolio and may cause PIMCO to restrict or prohibit participation in certain investments. There is no guarantee that the investment objective of the Portfolio will be achieved.

High Yield Risk  is the risk that high yield securities and unrated securities of similar credit quality (commonly known as “junk bonds”) are subject to greater levels of credit, call and liquidity risks. High yield securities are considered primarily speculative with respect to the issuer’s continuing ability to make principal and interest payments, and may be more volatile than higher-rated securities of similar maturity.

Currency Risk  is the risk that foreign (non-U.S.) currencies will change in value relative to the U.S. dollar and affect the Portfolio’s investments in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, or in derivatives that provide exposure to, foreign (non-U.S.) currencies.

Leveraging Risk  is the risk that certain transactions of the Portfolio, such as reverse repurchase agreements, loans of portfolio securities, and the use of when-issued, delayed delivery or forward commitment transactions, or derivative instruments, may give rise to leverage, magnifying gains and losses and causing the Portfolio to be more volatile than if it had not been leveraged. This means that leverage entails a heightened risk of loss.

Issuer Risk  is the risk that the value of a security may decline for a reason directly related to the issuer, such as management performance, major litigation, investigations or other controversies, changes in financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives, financial leverage, reputation or reduced demand for the issuer’s goods or services.

Turnover Risk  is the risk that high levels of portfolio turnover may increase transaction costs and taxes and may lower investment performance.

Municipal Securities Risk  is the risk that investing in municipal securities subjects the Portfolio to certain risks, including variations in the quality of municipal securities, both within a particular classification and between classifications. The rates of return on municipal securities can depend on a variety of factors, including general money market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue.

SEMIANNUAL REPORT JUNE 30, 2023 123

Notes to Financial Statements (Cont.)

Municipal Project-Specific Risk  is the risk that the Portfolio may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of specific projects (such as those relating to education, health care, housing, transportation, and utilities), industrial development bonds, or in bonds from issuers in a single state.

Municipal Bond Market Risk  is the risk that the Portfolio may be adversely affected due to factors such as limited amount of public information available regarding the municipal bonds held in the Portfolio as compared to that for corporate equities or bonds, legislative changes and local and business developments, general conditions of the municipal bond market, the size of the particular offering, the rating of the issue and the maturity of the obligation.

California State-Specific Risk  is the risk that the Portfolio, to the extent it concentrates its investments in California municipal bonds, may be affected significantly by economic, regulatory or political developments affecting the ability of California issuers to pay interest or repay principal.

New York State-Specific Risk  is the risk that the Portfolio, to the extent it concentrates its investments in New York municipal bonds, may be affected significantly by economic, regulatory or political developments affecting the ability of New York issuers to pay interest or repay principal.

AMT Bonds Risk  is the risk that “AMT Bonds,” which are municipal securities that pay interest that is taxable under the federal alternative minimum tax applicable to noncorporate taxpayers, may expose the Portfolio to certain risks in addition to those typically associated with municipal bonds. Interest or principal on AMT Bonds paid out of current or anticipated revenues from a specific project or specific asset may be adversely impacted by declines in revenue from the project or asset. Declines in general business activity could also affect the economic viability of facilities that are the sole source of revenue to support AMT Bonds. In this regard, AMT Bonds may entail greater risks than general obligation municipal bonds. For shareholders subject to the federal alternative minimum tax, a portion of the Portfolio’s distributions may not be exempt from gross federal income, which may give rise to alternative minimum tax liability.

Sovereign Debt Risk  is the risk that investments in fixed income instruments issued by sovereign entities may decline in value as a result of default or other adverse credit event resulting from an issuer’s inability or unwillingness to make principal or interest payments in a timely fashion.

Inflation/Deflation Risk  is the risk that the value of assets or income from the Portfolio’s investments will be worth less in the future as inflation decreases the value of payments at future dates. As inflation increases, the real value of the Portfolio’s investments could decline. Deflation risk is the risk that prices throughout the economy decline over time. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Portfolio’s investments.

Contingent Convertible Securities Risk  is the risk of investing in contingent convertible securities, including the risk that interest payments will be cancelled by the issuer or a regulatory authority, the risk of ranking junior to other creditors in the event of a liquidation or other bankruptcy-related event as a result of holding subordinated debt, the risk of the Portfolio’s investment becoming further subordinated as a result of conversion from debt to equity, the risk that principal amount due can be

written down to a lesser amount (including potentially to zero), and the general risks applicable to fixed income investments, including interest rate risk, credit risk, market risk and liquidity risk, any of which could result in losses to the Portfolio.

LIBOR Transition Risk  is the risk related to the anticipated discontinuation and replacement of the London Interbank Offered Rate (“LIBOR”). Certain instruments held by the Portfolio rely or relied in some fashion upon LIBOR. Although the transition process away from LIBOR for most instruments has been completed, some LIBOR use is continuing and there are potential effects related to the transition away from LIBOR or the continued use of LIBOR on a Portfolio or on certain instruments in which the Portfolio invests, which can be difficult to ascertain could result in losses to a Portfolio.

Collateralized Loan Obligations Risk  is the risk that investing in collateralized loan obligations (“CLOs”) and other similarly structured investments exposes the Portfolio to heightened credit risk, interest rate risk, liquidity risk, market risk and prepayment and extension risk, as well as the risk of default on the underlying asset. In addition, investments in CLOs carry additional risks including, but not limited to, the risk that: (i) distributions from the collateral may not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the Portfolio may invest in tranches of CLOs that are subordinate to other tranches; (iv) the structure and complexity of the transaction and the legal documents could lead to disputes among investors regarding the characterization of proceeds; and (v) the CLO’s manager may perform poorly.

(b) Other Risks

In general, a Portfolio may be subject to additional risks, including, but not limited to, risks related to government regulation and intervention in financial markets, operational risks, risks associated with financial, economic and global market disruptions, and cyber security risks. Please see a Portfolio’s Prospectus and Statement of Additional Information for a more detailed description of the risks of investing in a Portfolio. Please see the Important Information section of this report for additional discussion of certain regulatory and market developments that may impact a Portfolio’s performance.

Market Disruption Risk  is the risk of investment and operational risks associated with financial, economic and other global market developments and disruptions, including those arising from war, terrorism, market manipulation, government interventions, defaults and shutdowns, political changes or diplomatic developments, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics) and natural/environmental disasters, which can all negatively impact the securities markets, interest rates, auctions, secondary trading, ratings, credit risk, inflation, deflation or other factors relating to the Portfolio’s investments or PIMCO’s operations and cause a Portfolio to lose value. Furthermore, events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. These events can also impair the technology and other operational systems upon which a Portfolio’s service providers, including PIMCO as a Portfolio’s investment adviser, rely, and could otherwise disrupt a Portfolio’s service providers’ ability to fulfill their obligations to a Portfolio.

Government Intervention in Financial Markets  is the risk that federal, state, and other governments, their regulatory agencies, or self-regulatory organizations may take actions that affect

SEMIANNUAL REPORT JUNE 30, 2023 125

Notes to Financial Statements (Cont.)

the regulation of the instruments in which a Portfolio invests, or the issuers of such instruments, in ways that are unforeseeable. Legislation or regulation may also change the way in which a Portfolio itself is regulated. Such legislation or regulation could limit or preclude a Portfolio’s ability to achieve its investment objective. Furthermore, volatile financial markets can expose a Portfolio to greater market and liquidity risk and potential difficulty in valuing portfolio instruments held by the Portfolio. The value of a Portfolio’s holdings is also generally subject to the risk of future local, national, or global economic disturbances based on unknown weaknesses in the markets in which a Portfolio invests. In addition, it is not certain that the U.S. Government will intervene in response to a future market disturbance and the effect of any such future intervention cannot be predicted. It is difficult for issuers to prepare for the impact of future financial downturns, although companies can seek to identify and manage future uncertainties through risk management programs.

Regulatory Risk  is the risk that financial entities, such as investment companies and investment advisers, are generally subject to extensive government regulation and intervention. Government regulation and/ or intervention may change the way a Portfolio is regulated, affect the expenses incurred directly by a Portfolio and the value of its investments, and limit and/or preclude a Portfolio’s ability to achieve its investment objective. Government regulation may change frequently and may have significant adverse consequences. Moreover, government regulation may have unpredictable and unintended effects.

Operational Risk  is the risk arising from factors such as processing errors, human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel and errors caused by third-party service providers. The occurrence of any of these failures, errors or breaches could result in a loss of information, regulatory scrutiny, reputational damage or other events, any of which could have a material adverse effect on a Portfolio. While a Portfolio seeks to minimize such events through controls and oversight, there may still be failures that could cause losses to the Portfolio.

Cyber Security Risk  is the risk that, as the use of technology has become more prevalent in the course of business, the Portfolios have become potentially more susceptible to operational and information security risks resulting from breaches in cyber security. A breach in cyber security refers to both intentional and unintentional cyber events that may, among other things, cause a Portfolio to lose proprietary information, suffer data corruption and/or destruction or lose operational capacity, result in the unauthorized release or other misuse of confidential information, or otherwise disrupt normal business operations. Cyber security failures or breaches may result in financial losses to a Portfolio and its shareholders. These failures or breaches may also result in disruptions to business operations, potentially resulting in financial losses; interference with a Portfolio’s ability to calculate its net asset value, process shareholder transactions or otherwise transact business with shareholders; impediments to trading; violations of applicable privacy and other laws; regulatory fines; penalties; third party claims in litigation; reputational damage; reimbursement or other compensation costs; additional compliance and cyber security risk management costs and other adverse consequences. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. There is also a risk that cyber security breaches may not be detected. The Portfolios and their shareholders may suffer losses as a result of a cyber security breach related to the Portfolios, their service providers, trading counterparties or the issuers in which a Portfolio invests.

8. MASTER NETTING ARRANGEMENTS

A Portfolio may be subject to various netting arrangements (“Master Agreements”) with select counterparties. Master Agreements govern the terms of certain transactions, and are intended to reduce the counterparty risk associated with relevant transactions by specifying credit protection mechanisms and providing standardization that is intended to improve legal certainty. Each type of Master Agreement governs certain types of transactions. Different types of transactions may be traded out of different legal entities or affiliates of a particular organization, resulting in the need for multiple agreements with a single counterparty. As the Master Agreements are specific to unique operations of different asset types, they allow a Portfolio to close out and net its total exposure to a counterparty in the event of a default with respect to all the transactions governed under a single Master Agreement with a counterparty. For financial reporting purposes the Statements of Assets and Liabilities generally present derivative assets and liabilities on a gross basis, which reflects the full risks and exposures prior to netting.

Master Agreements can also help limit counterparty risk by specifying collateral posting arrangements at pre-arranged exposure levels. Under most Master Agreements, collateral is routinely transferred if the total net exposure to certain transactions (net of existing collateral already in place) governed under the relevant Master Agreement with a counterparty in a given account exceeds a specified threshold, which typically ranges from zero to $250,000 depending on the counterparty and the type of Master Agreement. United States Treasury Bills and U.S. dollar cash are generally the preferred forms of collateral, although other securities may be used depending on the terms outlined in the applicable Master Agreement. Securities and cash pledged as collateral are reflected as assets on the Statements of Assets and Liabilities as either a component of Investments at value (securities) or Deposits with counterparty. Cash collateral received is not typically held in a segregated account and as such is reflected as a liability on the Statements of Assets and Liabilities as Deposits from counterparty. The market value of any securities received as collateral is not reflected as a component of NAV. A Portfolio’s overall exposure to counterparty risk can change substantially within a short period, as it is affected by each transaction subject to the relevant Master Agreement.

Master Repurchase Agreements and Global Master Repurchase Agreements (individually and collectively “Master Repo Agreements”) govern repurchase, reverse repurchase, and certain sale-buyback transactions between a Portfolio and select counterparties. Master Repo Agreements maintain provisions for, among other things, initiation, income payments, events of default, and maintenance of collateral. The market value of transactions under the Master Repo Agreement, collateral pledged or received, and the net exposure by counterparty as of period end are disclosed in the Notes to Schedules of Investments.

Master Securities Forward Transaction Agreements (“Master Forward Agreements”) govern certain forward settling transactions, such as TBA securities, delayed-delivery or certain sale-buyback transactions by and between a Portfolio and select counterparties. The Master Forward Agreements maintain provisions for, among other things, transaction initiation and confirmation, payment and transfer, events of default, termination, and maintenance of collateral. The market value of forward settling transactions, collateral pledged or received, and the net exposure by counterparty as of period end is disclosed in the Notes to Schedules of Investments.

SEMIANNUAL REPORT JUNE 30, 2023 127

Notes to Financial Statements (Cont.)

Customer Account Agreements and related addenda govern cleared derivatives transactions such as futures, options on futures, and cleared OTC derivatives. Such transactions require posting of initial margin as determined by each relevant clearing agency which is segregated in an account at a futures commission merchant (“FCM”) registered with the Commodity Futures Trading Commission. In the United States, counterparty risk may be reduced as creditors of an FCM cannot have a claim to Portfolio assets in the segregated account. Portability of exposure reduces risk to the Portfolios. Variation margin, which reflects changes in market value, is generally exchanged daily, but may not be netted between futures and cleared OTC derivatives unless the parties have agreed to a separate arrangement in respect of portfolio margining. The market value or accumulated unrealized appreciation (depreciation), initial margin posted, and any unsettled variation margin as of period end are disclosed in the Notes to Schedules of Investments.

International Swaps and Derivatives Association, Inc. Master Agreements and Credit Support Annexes (“ISDA Master Agreements”) govern bilateral OTC derivative transactions entered into by a Portfolio with select counterparties. ISDA Master Agreements maintain provisions for general obligations, representations, agreements, collateral posting and events of default or termination. Events of termination include conditions that may entitle counterparties to elect to terminate early and cause settlement of all outstanding transactions under the applicable ISDA Master Agreement. Any election to terminate early could be material to the financial statements. The ISDA Master Agreement may contain additional provisions that add counterparty protection beyond coverage of existing daily exposure if the counterparty has a decline in credit quality below a predefined level or as required by regulation. Similarly, if required by regulation, the Portfolios may be required to post additional collateral beyond coverage of daily exposure. These amounts, if any, may (or if required by law, will) be segregated with a third-party custodian. To the extent the Portfolios are required by regulation to post additional collateral beyond coverage of daily exposure, they could potentially incur costs, including in procuring eligible assets to meet collateral requirements, associated with such posting. The market value of OTC financial derivative instruments, collateral received or pledged, and net exposure by counterparty as of period end are disclosed in the Notes to Schedules of Investments.

9. FEES AND EXPENSES

(a) Investment Advisory Fee  The Trust entered into an Investment Advisory Contract with the Adviser (the “Advisory Contract”) pursuant to which the Adviser serves as the investment adviser to each Portfolio. The Adviser does not receive investment advisory or other fees from the Portfolios or the Trust (although PIMCO may receive compensation under the Advisory Contract with respect to future series of the Trust). The financial statements reflect the fact that no investment management fees or expenses are incurred by the Portfolios.

Each Portfolio is an integral part of one or more “wrap-fee” programs, including those sponsored by investment advisers and/or broker-dealers unaffiliated with the Portfolios or PIMCO. Participants in these programs pay a “wrap” fee to the sponsor of the program. PIMCO may receive fees or other benefits from or through its relationships with the sponsors of such wrap-fee programs for which the Portfolios are an investment option.

(b) Supervisory and Administration Fee  Pursuant to the Supervision and Administration Agreement with PIMCO (the “Administration Agreement”), PIMCO also serves as administrator to the Portfolios

128 PIMCO MANAGED ACCOUNTS TRUST

(Unaudited)

June 30, 2023

(in this capacity, PIMCO is referred to as the “Administrator”). Under the Administration Agreement, the Administrator, at its expense, is required to procure most supervisory and administrative services required by the Portfolios including, but not limited to, expenses of most third-party service providers (e.g., audit, custodial, legal, transfer agency, printing) and other expenses, such as those associated with insurance, proxy solicitations and mailings for shareholder meetings, tax services, valuation services and other services required for the Portfolios’ daily operations. Under the Administration Agreement, the Administrator has agreed to provide or procure these services, and to bear the expenses associated with these services at no charge to the Portfolios. In addition, PIMCO has entered into an expense limitation agreement with the Trust pursuant to which it has agreed to pay or reimburse certain other expenses of the Portfolios, as discussed in more detail below. The Administrator does not receive any administration or other fees from the Portfolios or the Trust for serving as administrator to the Portfolios (although the Administrator may receive compensation under the Administration Agreement with respect to future series of the Trust). The Trust pays no compensation directly to any Trustee or any other officer who is affiliated with the Administrator, all of whom receive remuneration for their services to the Trust from the Administrator or its affiliates.

The Trust is responsible for the following expenses: (i) salaries and other compensation or expenses, including travel expenses, of any of the Trust’s executive officers and employees, if any, who are not officers, directors, shareholders, members, partners or employees of the Administrator or its subsidiaries or affiliates; (ii) taxes and governmental fees, if any, levied against the Trust or any of its Portfolios; (iii) brokerage fees and commissions, and other portfolio transaction expenses incurred for any of the Portfolios; (iv) expenses of each Portfolio’s securities lending (if any), including any securities lending agent fees, as governed by a separate securities lending agreement; (v) costs, including interest expenses, of borrowing money or engaging in other types of leverage financing including, without limitation, through the use by a Portfolio of reverse repurchase agreements, tender option bonds, bank borrowings and credit facilities; (vi) fees and expenses of any underlying funds or other pooled vehicles in which a Portfolio invests; (vii) dividend and interest expenses on short positions taken by the Portfolios; (viii) fees and expenses, including travel expenses, and fees and expenses of legal counsel retained for their benefit, of Trustees who are not officers, employees, partners, shareholders or members of PIMCO or its subsidiaries or affiliates; (ix) extraordinary expenses, including extraordinary legal expenses, as may arise including expenses incurred in connection with litigation, proceedings, other claims and the legal obligations of the Trust to indemnify its trustees, officers, employees, shareholders, distributors, and agents with respect thereto; (x) to the extent permitted by the Board, organizational and offering expenses of the Trust and the Portfolios and any expenses which are capitalized in accordance with generally accepted accounting principles; and (xi) any expenses allocated or allocable to a specific class of shares of a Portfolio, including fees paid pursuant to an administrative services or distribution plan.

(c) Distribution Contract  The Trust has entered into a distribution contract with PIMCO Investments LLC (the “Distributor”), a wholly-owned subsidiary of PIMCO, pursuant to which the Distributor serves as the distributor and principal underwriter of the Portfolios’ shares (the “Distribution Contract”). The Distributor does not receive any distribution or other fees from the Portfolios or the Trust for serving as the distributor and principal underwriter of the Portfolios’ shares (although the Distributor may receive compensation under the Distribution Contract with respect to future series of the Trust).

(d) Expense Limitation Agreement  The Adviser has contractually agreed pursuant to an expense limitation agreement (the “Expense Limitation Agreement”) to bear the expenses of or make payments to each Portfolio to the extent that, for any calendar month, “Specified Expenses”, as defined in the Expense Limitation Agreement of such Portfolio would exceed 0.00%. “Specified Expenses” of a Portfolio means all expenses incurred by the Portfolio, including organizational and offering expenses and expenses associated with obtaining or maintaining a Legal Entity Identifier, but excluding any brokerage fees and commissions and other portfolio transaction expenses, costs, including interest expenses, of borrowing money or engaging in other types of leverage financing, including, without limitation, through reverse repurchase agreements, tender option bonds, bank borrowings and credit facilities, fees and expenses of any underlying Portfolios or other pooled vehicles in which the Portfolio invests, taxes, governmental fees, dividends and interest on short positions, and extraordinary expenses, including extraordinary legal expenses. This Expense Limitation Agreement shall continue in effect, unless sooner terminated by the Board, for so long as the Adviser serves as the investment adviser to the applicable Portfolio pursuant to the Advisory Contract. The waivers, if any, are reflected on the Statements of Operations as a component of Waiver and/or Reimbursement by PIMCO.

10. RELATED PARTY TRANSACTIONS

The Adviser, Administrator, and Distributor are related parties. Fees paid to these parties are disclosed in Note 9, Fees and Expenses, and the accrued related party fee amounts are disclosed on the Statements of Assets and Liabilities.

Certain Portfolios are permitted to purchase or sell securities from or to certain related affiliated funds under specified conditions outlined in procedures adopted by the Board. The procedures have been designed to ensure that any purchase or sale of securities by the Portfolios from or to another fund or portfolio that are, or could be, considered an affiliate, or an affiliate of an affiliate, by virtue of having a common investment adviser (or affiliated investment advisers), common Trustees and/or common officers complies with applicable SEC rules and interpretations under the Act. Further, as defined under the procedures, each transaction is effected at the current market price. Purchases and sales of securities pursuant to applicable SEC rules and interpretations under the Act for the period ended June 30, 2023, were as follows (amounts in thousands^†):

Portfolio Name	Purchases		Sales		Realized Gain/Loss
Fixed Income SHares: Series C	$	6,253	$	6,151	$	(2,006	)
Fixed Income SHares: Series TE		175		51		(1	)

^†  A zero balance may reflect actual amounts rounding to less than one thousand.

11. GUARANTEES AND INDEMNIFICATIONS

Under the Trust’s organizational documents, each Trustee and officer is indemnified, to the extent permitted by the Act, against certain liabilities that may arise out of performance of their duties to the Portfolios. Additionally, in the normal course of business, the Portfolios enter into contracts that contain a variety of indemnification clauses. The Portfolios’ maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Portfolios that have not yet occurred. However, the Portfolios have not had prior claims or losses pursuant to these contracts.

12. PURCHASES AND SALES OF SECURITIES

The length of time a Portfolio has held a particular security is not generally a consideration in investment decisions. A change in the securities held by a Portfolio is known as “portfolio turnover.” Each Portfolio may engage in frequent and active trading of portfolio securities to achieve its investment objective(s), particularly during periods of volatile market movements. High portfolio turnover may involve correspondingly greater transaction costs, including brokerage commissions or dealer mark-ups and other transaction costs on the sale of securities and reinvestments in other securities, which are borne by the Portfolio. Such sales may also result in realization of taxable capital gains, including short-term capital gains (which are generally taxed at ordinary income tax rates when distributed to shareholders). The transaction costs associated with portfolio turnover may adversely affect a Portfolio’s performance. The portfolio turnover rates are reported in the Financial Highlights.

Purchases and sales of securities (excluding short-term investments) for the period ended June 30, 2023, were as follows (amounts in thousands^†):

	U.S. Government/Agency				All Other
Portfolio Name	Purchases		Sales		Purchases		Sales

Fixed Income SHares: Series TE		925		0		17,939		19,891

^†  A zero balance may reflect actual amounts rounding to less than one thousand.

13. SHARES OF BENEFICIAL INTEREST

The Trust may issue an unlimited number of shares of beneficial interest with a $0.001 par value.

14. REGULATORY AND LITIGATION MATTERS

The Portfolios are not named as defendants in any material litigation or arbitration proceedings and are not aware of any material litigation or claim pending or threatened against them.

The foregoing speaks only as of the date of this report.

15. FEDERAL INCOME TAX MATTERS

Each Portfolio intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code (the “Code”) and distribute all of its taxable income and net realized gains, if applicable, to shareholders. Accordingly, no provision for Federal income taxes has been made. Due to the timing of when distributions are made by a Portfolio, the Portfolio may be subject to an excise tax of 4% of the amount by which 98% of the Portfolio’s annual taxable income and 98.2% of net realized gains exceed the distributions from such taxable income and realized gains for the calendar year.

A Portfolio may be subject to local withholding taxes, including those imposed on realized capital gains. Any applicable foreign capital gains tax is accrued daily based upon net unrealized gains, and may be payable following the sale of any applicable investments.

June 30, 2023

In accordance with U.S. GAAP, the Adviser has reviewed the Portfolios’ tax positions for all open tax years. As of June 30, 2023, the Portfolios have recorded no liability for net unrecognized tax benefits relating to uncertain income tax positions they have taken or expect to take in future tax returns.

The Portfolios file U.S. federal, state, and local tax returns as required. The Portfolios’ tax returns are subject to examination by relevant tax authorities until expiration of the applicable statute of limitations, which is generally three years after the filing of the tax return but which can be extended to six years in certain circumstances. Tax returns for open years have incorporated no uncertain tax positions that require a provision for income taxes.

Under the Regulated Investment Company Modernization Act of 2010, a Portfolio is permitted to carry forward any new capital losses for an unlimited period. Additionally, such capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term under previous law.

As of their last fiscal year ended December 31, 2022, the Portfolios had the following post-effective capital losses with no expiration (amounts in thousands^†):

	Short-Term		Long-Term
Fixed Income SHares: Series C	$	194,979	$	22,744
Fixed Income SHares: Series LD		0		0

Approval of Investment Management Agreement

PMAT

The Investment Company Act of 1940, as amended (the “1940 Act”), requires that the Board of Trustees (the “Board” or the “Trustees”), including a majority of the Trustees who are not “interested persons,” as that term is defined in the 1940 Act (the “Independent Trustees”), of PIMCO Managed Accounts Trust (“PMAT”), voting separately, annually approve the continuation of the Investment Advisory Contract between PMAT, on behalf of each of its series (each, a “Portfolio” and, collectively, the “Portfolios”), and Pacific Investment Management Company LLC (“PIMCO”) (the “Agreement”). At an in-person meeting held on June 14, 2023 (the “Approval Meeting”), the Board, including the Independent Trustees, considered and unanimously approved the continuation of the Agreement for an additional one-year period commencing on August 1, 2023.

In addition to the Approval Meeting, the Contracts Committee (the “Committee”) and the Performance Committee of the Board held a joint meeting on May 19, 2023 to discuss materials provided by PIMCO in connection with the Trustees’ review of the Agreements. The annual contract review process also involved multiple discussions and meetings with members of the Committee and the full Committee (the Approval Meeting, together with such discussions and meetings, the “Contract Renewal Meetings”). Throughout the process, the Independent Trustees received legal advice from independent legal counsel that is experienced in 1940 Act matters and independent of PIMCO (“Independent Counsel”), and with whom they met separately from PIMCO during the Contract Renewal Meetings. Representatives from PIMCO attended portions of the Contract Renewal Meetings and responded to questions from the Independent Trustees. The Committee also received and reviewed a memorandum from Independent Counsel regarding the Trustees’ responsibilities in considering the Agreement and the fees paid thereunder.

In connection with their deliberations regarding the proposed continuation of the Agreement for each Portfolio, the Board, including the Independent Trustees, considered such information and factors as they believed, in light of the legal advice furnished to them and their own business judgment, to reasonably be necessary to evaluate the terms of the Agreements. The Trustees also considered the nature, quality and extent of the various services performed by PIMCO under the Agreement.

In evaluating the Agreement, the Board, including the Independent Trustees, reviewed extensive materials provided by PIMCO in response to questions, inclusive of follow-up inquiries, submitted by the Independent Trustees and Independent Counsel. The Board also met with senior representatives of PIMCO regarding its personnel, operations, and estimated profitability as they relate to the Portfolios. The Trustees also considered the broad range of information relevant to the annual contract review that is provided to the Board (including its various standing committees) at meetings throughout the year, including reports on investment performance, risks, and other portfolio information for each Portfolio, including any use of derivatives, as well as periodic reports on, among other matters, pricing and valuation; quality and cost of portfolio trade execution; compliance; and shareholder and other services provided by PIMCO and its affiliates. To assist with their review, the Trustees also reviewed information regarding the investment performance for each Portfolio and certain composites comprised of separate accounts managed by PIMCO that invest in the Portfolios, along with associated benchmark indices for such separate accounts, as well as the estimated profitability to PIMCO with respect to the Portfolios (taking into account profitability estimates of related separate accounts) for the one-year period ended December 31, 2022.

(Unaudited)

The Trustees’ conclusions as to the continuation of the Agreement were based on a comprehensive consideration of all information provided to the Trustees during the Contract Renewal Meetings and throughout the year and were not the result of any single factor. Some of the factors that figured particularly in the Trustees’ deliberations are described below, although individual Trustees may have evaluated the information presented differently from one another, attributing different weights to various factors. The Trustees evaluated information available to them on a Portfolio-by-Portfolio basis, and their determinations were made separately in respect of each Portfolio.

Nature, Extent and Quality of Services

As part of their review, the Trustees received and considered descriptions of various functions performed by PIMCO for the Portfolios, such as portfolio management, compliance monitoring, portfolio trading practices, and oversight of third-party service providers. They also considered information regarding the overall organization and business functions of PIMCO, including, without limitation, information regarding senior management, portfolio managers and other personnel providing investment management, administrative and other services, and general corporate ownership and business operations unrelated to the Portfolios. The Trustees examined PIMCO’s abilities to provide high-quality investment management and other services to the Portfolios. Among other information, the Trustees considered the investment philosophy and research and decision-making processes of PIMCO; the experience of key advisory personnel of PIMCO responsible for portfolio management of the Portfolios; recent changes to the named portfolio managers of the Portfolios, as applicable; the ability of PIMCO to attract and retain capable personnel; the background and capabilities of the senior management and staff of PIMCO; the general process or philosophy for determining employee compensation; and the operational infrastructure, including technology and systems and cybersecurity measures, of PIMCO.

In addition, the Trustees noted the extensive range of services that PIMCO provides to the Portfolios beyond investment management services. In this regard, the Trustees reviewed the extent and quality of PIMCO’s services with respect to regulatory compliance and its ability to comply with the investment policies of the Portfolios; the compliance programs and risk controls of PIMCO (including the implementation of new policies and programs); the specific contractual obligations of PIMCO pursuant to the Agreement; the nature, extent, and quality of the investment advisory services PIMCO is responsible for providing to the Portfolios; PIMCO’s risk management function; and conditions that might affect PIMCO’s ability to provide high-quality services to the Portfolios in the future under the Agreement, including, but not limited to, PIMCO’s financial condition and operational stability. The Trustees also took into account the entrepreneurial, business and other risks that PIMCO has undertaken as investment manager and sponsor of the Portfolios for which it receives no direct management fee. Specifically, the Trustees considered that PIMCO’s responsibilities include continual management of investment, operational, enterprise, legal, regulatory, and compliance risks as they relate to the Portfolios. The Trustees also noted PIMCO’s activities under its contractual obligation to coordinate, oversee and supervise the Portfolios’ various outside service providers, including its negotiation of certain service providers’ fees and its due diligence and evaluation of service providers’ infrastructure, cybersecurity programs, compliance programs, and business continuity programs, among other matters. The Trustees also considered PIMCO’s ongoing development of its own infrastructure and information technology, including its

SEMIANNUAL REPORT JUNE 30, 2023 135

Approval of Investment Management Agreement (Cont.)

proprietary software and applications, to support the Portfolios through, among other things, cybersecurity, business continuity planning, and risk management.

After their review and deliberations, the Trustees concluded that the nature, extent and quality of the overall services provided by PIMCO under the Agreement were appropriate.

Fee and Expense Information

The Trustees also gave substantial consideration to the fact that, with respect to each Portfolio, no fees are payable to PIMCO from the Portfolios under the Agreement, and that PIMCO has entered into an Expense Limitation Agreement with PMAT, on behalf of each Portfolio, pursuant to which PIMCO waives all fees and/or pays or reimburses all expenses of the Portfolios, except extraordinary expenses, including extraordinary legal expenses, and expenses incurred as a result of portfolio investments, such as any brokerage fees and commissions and other portfolio transaction expenses, costs, including interest expenses, of borrowing money or engaging in other types of leverage financing, fees and expenses of any underlying funds or other pooled vehicles in which the Portfolios invest, taxes, governmental fees and dividends and interest on short positions.

Performance Information

The Trustees also considered the performance of each Portfolio as compared to the performance of a composite comprised of separate accounts managed by PIMCO that invest in the Portfolio, along with associated benchmark indices for such separate accounts. The Trustees noted that because the Portfolios are intended to form only a portion of an overall investment strategy and were developed exclusively for use within separately managed accounts, comparisons to the performance of traditional stand-alone funds or accounts managed by PIMCO would produce limited relevant information. The Trustees noted that the Series C Portfolio underperformed the performance of the associated benchmark for the one-, three-, five-, and ten-year periods ending December 31, 2022; the Series M Portfolio outperformed the performance of the associated benchmark for the three-, five-, and ten-year periods ending December 31, 2022 but underperformed the performance of the associated benchmark for the one-year period ending December 31, 2022; the Series R and Series TE Portfolios each outperformed the performance of the associated benchmarks for the five- and ten-year periods ending December 31, 2022 but underperformed the performance of the associated benchmarks for the one- and three-year periods ending December 31, 2022; and the Series LD Portfolio outperformed the performance of the associated benchmark for the three- and five-year periods ending December 31, 2022 but underperformed the performance of the associated benchmark for the one-year period ending December 31, 2022. In addition, the Trustees considered matters bearing on the Portfolios and their advisory arrangements at their meetings throughout the year, including a review of performance data at each regular meeting (by both the Board and its Performance Committee).

Profitability, Economies of Scale, and Fall-out Benefits

Because the Portfolios do not pay fees directly, the Trustees did not place emphasis on the extent to which economies of scale would be realized due to potential growth of assets in the Portfolios or whether fee and expense levels reflect economies of scale for the Portfolios’ shareholders.

The Trustees considered the fact that PIMCO and its affiliates may benefit from their relationships with the sponsors of wrap programs for which the Portfolios are an investment option. They noted

136 PIMCO MANAGED ACCOUNTS TRUST

(Unaudited)

such benefits include the receipt by PIMCO and its affiliates of fees paid by the sponsor of the wrap program based on assets under management of the wrap program. Additionally, the Trustees considered so-called “fall-out benefits” to PIMCO, such as reputational value derived from serving as investment adviser to the Portfolios and research, statistical and quotation services PIMCO may receive from broker-dealers executing the Portfolios’ portfolio transactions on an agency basis.

The Trustees also considered the amounts paid by the sponsors of the “wrap” programs to PIMCO and/or its affiliates with respect to wrap account assets invested in the Portfolios, as well as the fees “imputed” to PIMCO, for purposes of arriving at an estimate of profitability arising from PIMCO’s and its affiliates’ relationships with the Portfolios. Among other information, the Trustees took into account explanations from PIMCO regarding how certain of PIMCO’s corporate and shared expenses were allocated among the Portfolios and other funds and accounts managed by PIMCO for purposes of developing profitability estimates. Based on the profitability analyses provided by PIMCO, the Trustees determined, taking into account the various assumptions made, that such profitability did not appear to be excessive.

Conclusion

After reviewing these and other factors described herein, including that no fees are payable under the Agreement, the Trustees concluded, with respect to each Portfolio, within the context of their overall conclusions regarding the Agreement, and based on the information provided and related representations made by management, and in their business judgment, that they were satisfied with PIMCO’s responses and efforts relating to the investment performance of the Portfolios. Based on their evaluation of factors that they deemed to be material, including, but not limited to, those factors described above, the Board, including the Independent Trustees, unanimously concluded that the continuation of the Agreement was in the interests of each Portfolio and its shareholders, and should be approved.

Liquidity Risk Management Program

(Unaudited)

In compliance with Rule 22e-4 (the “Liquidity Rule”) under the Investment Company Act of 1940, as amended (“1940 Act”), PIMCO Managed Accounts Trust (the “Trust”) has adopted and implemented a liquidity risk management program (the “Program”) for each series of the Trust (each a “Portfolio” and collectively, the “Portfolios”) not regulated as a money market fund under 1940 Act Rule 2a-7, which is reasonably designed to assess and manage the Portfolios’ liquidity risk. The Trust’s Board of Trustees (the “Board”) previously approved the designation of the PIMCO Liquidity Risk Committee (the “Administrator”) as Program administrator. The PIMCO Liquidity Risk Committee consists of senior members from certain PIMCO business areas, such as Portfolio Risk Management, Americas Operations, Compliance, Account Management and Portfolio Management, and is advised by members of PIMCO Legal.

A Portfolio’s “liquidity risk” is the risk that the Portfolio could not meet requests to redeem shares issued by the Portfolio without significant dilution of the remaining investors’ interests in the Portfolio. In accordance with the Program, each Portfolio’s liquidity risk is assessed no less frequently than annually taking into consideration a variety of factors, including, as applicable, the Portfolio’s investment strategy and liquidity of portfolio investments, cash flow projections, and holdings of cash and cash equivalents, as well as borrowing arrangements and other funding sources. Certain factors are considered under both normal and reasonably foreseeable stressed conditions. Each portfolio investment is classified into one of four liquidity categories (including “highly liquid investments” and “illiquid investments,” discussed below) based on a determination of the number of days it is reasonably expected to take to convert the investment to cash, or sell or dispose of the investment, in current market conditions without significantly changing the investment’s market value. Each Portfolio has adopted a “Highly Liquid Investment Minimum” (or “HLIM”), which is a minimum amount of Portfolio net assets to be invested in highly liquid investments that are assets. As required under the Liquidity Rule, each Portfolio’s HLIM is periodically reviewed, no less frequently than annually, and the Portfolios have adopted policies and procedures for responding to a shortfall of a Portfolio’s highly liquid investments below its HLIM. The Liquidity Rule also limits the Portfolios’ investments in illiquid investments by prohibiting a Portfolio from acquiring any illiquid investment if, immediately after the acquisition, the Portfolio would have invested more than 15% of its net assets in illiquid investments that are assets. Certain non-public reporting is generally required if a Portfolio’s holdings of illiquid investments that are assets were to exceed 15% of Portfolio net assets.

At a meeting of the Board held on March 23, 2023, the Board received a report (the “Report”) from the Administrator addressing the Program’s operation and assessing the adequacy and effectiveness of its implementation for the 12-month period ended December 31, 2022. The Report reviewed the operation of the Program’s components during such period and stated that the Program is operating effectively to assess and manage each Portfolio’s liquidity risk and that the Program has been and continues to be adequately and effectively implemented to monitor and, as applicable, respond to the Portfolios’ liquidity developments. This has remained true for the 12-month period ended June 30, 2023.
